switchdev: convert fib_ipv4_add/del over to switchdev_port_obj_add/del
The IPv4 FIB ops convert nicely to the switchdev objs and we're left with
only four switchdev ops: port get/set and port add/del. Other objs will
follow, such as FDB. So go ahead and convert IPv4 FIB over to switchdev
obj for consistency, anticipating more objs to come.

Like bridge_setlink, add switchdev wrapper to handle bridge_getlink and
call into port driver to get port attrs. For now, only BR_LEARNING and

away from ndo_dflt_bridge_getlink() and build the netlink skb directly in

bridge: restore br_setlink back to original
This is revert of:
commit 68e331c785b8 ("bridge: offload bridge port attributes to switch asic
if feature flag set")
Restore br_setlink back to original and don't call into SELF port driver.
rtnetlink.c:bridge_setlink() already does a call into port driver for SELF.
bridge set link cmd defaults to MASTER. From man page for bridge link set
cmd:
self link setting is configured on specified physical device
master link setting is configured on the software bridge (default)
The link setting has two values: the device-side value and the software
bridge-side value. These are independent and settable using the bridge
link set cmd by specifying some combination of [master] | [self].
Furthermore, the device-side and bridge-side settings have their own
initial value, viewable from bridge -d link show cmd.
Restoring br_setlink back to original makes rocker (the only in-kernel user
of SELF link settings) work as first implement: two-sided values.
It's true that when both MASTER and SELF are specified from the command,
two netlink notifications are generated, one for each side of the settings.
The user-space app can distiquish between the two notifications by
observing the MASTER or SELF flag.

switchdev: add new switchdev bridge setlink
Add new switchdev_port_bridge_setlink that can be used by drivers
implementing .ndo_bridge_setlink to set switchdev bridge attributes.
Basically turn the raw rtnl_bridge_setlink netlink into switchdev attr
sets. Proper netlink attr policy checking is done on the protinfo part of
the netlink msg.
Currently, for protinfo, only bridge port attrs BR_LEARNING and
BR_LEARNING_SYNC are parsed and passed to port driver.
For afspec, VLAN objs are passed so switchdev driver can set VLANs assigned
to SELF. To illustrate with iproute2 cmd, we have:
bridge vlan add vid 10 dev sw1p1 self master
To add VLAN 10 to port sw1p1 for both the bridge (master) and the device
(self).

switchdev: convert STP update to switchdev attr set
STP update is just a settable port attribute, so convert
switchdev_port_stp_update to an attr set.
For DSA, the prepare phase is skipped and STP updates are only done in the
commit phase. This is because currently the DSA drivers don't need to
allocate any memory for STP updates and the STP update will not fail to HW
(unless something horrible goes wrong on the MDIO bus, in which case the
prepare phase wouldn't have been able to predict anyway).

rocker: support prepare-commit transaction model
For rocker, support prepare-commit transaction model for setting attributes
(and for adding objects). This requires rocker to preallocate memory
needed for the commit up front in the prepare phase. Since rtnl_lock is
held between prepare-commit, store the allocated memory on a queue hanging
off of the rocker_port. Also, in prepare phase, do everything right up to
calling into HW. The same code paths are tranversed in the driver for both
prepare and commit phases. In some cases, any state modified in the
prepare phase must be reverted before returning so the commit phase makes
the same decisions.
As a consequence of holding rtnl_lock in process context for all attr sets
(and obj adds), all memory is GFP_KERNEL allocated and we don't need to
busy spin waiting for the device to complete the command. So the bulk of
this patch is simplifying the memory allocations to only use GFP_KERNEL and
to remove the nowait flag and busy spin loop.

switchdev: convert parent_id_get to switchdev attr get
Switch ID is just a gettable port attribute. Convert switchdev op
switchdev_parent_id_get to a switchdev attr.
Note: for sysfs and netlink interfaces, SWITCHDEV_ATTR_PORT_PARENT_ID is
called with SWITCHDEV_F_NO_RECUSE to limit switch ID user-visiblity to only
port netdevs. So when a port is stacked under bond/bridge, the user can
only query switch id via the switch ports, but not via the upper devices

switchdev: introduce get/set attrs ops
Add two new swdev ops for get/set switch port attributes. Most swdev
interactions on a port are gets or sets on port attributes, so rather than
adding ops for each attribute, let's define clean get/set ops for all
attributes, and then we can have clear, consistent rules on how attributes
propagate on stacked devs.
Add the basic algorithms for get/set attr ops. Use the same recusive algo
to walk lower devs we've used for STP updates, for example. For get,
compare attr value for each lower dev and only return success if attr
values match across all lower devs. For sets, set the same attr value for
all lower devs. We'll use a two-phase prepare-commit transaction model for
sets. In the first phase, the driver(s) are asked if attr set is OK. If
all OK, the commit attr set in second phase. A driver would NACK the
prepare phase if it can't set the attr due to lack of resources or support,
within it's control. RTNL lock must be held across both phases because
we'll recurse all lower devs first in prepare phase, and then recurse all
lower devs again in commit phase. If any lower dev fails the prepare
phase, we need to abort the transaction for all lower devs.
If lower dev recusion isn't desired, allow a flag SWITCHDEV_F_NO_RECURSE to
indicate get/set only work on port (lowest) device.

net_sched: gred: add TCA_GRED_LIMIT attribute
In a GRED qdisc, if the default "virtual queue" (VQ) does not have drop
parameters configured, then packets for the default VQ are not subjected
to RED and are only dropped if the queue is larger than the net_device's
tx_queue_len. This behavior is useful for WRED mode, since these packets
will still influence the calculated average queue length and (therefore)
the drop probability for all of the other VQs. However, for some drivers
tx_queue_len is zero. In other cases the user may wish to make the limit
the same for all VQs (including the default VQ with no drop parameters).
This change adds a TCA_GRED_LIMIT attribute to set the GRED queue limit,
in bytes, during qdisc setup. (This limit is in bytes to be consistent
with the drop parameters.) The default limit is the same as for a bfifo
queue (tx_queue_len * psched_mtu). If the drop parameters of any VQ are
configured with a smaller limit than the GRED queue limit, that VQ will
still observe the smaller limit instead.

MIPS: Fix a preemption issue with thread's FPU defaults
Fix "BUG: using smp_processor_id() in preemptible" reported in accesses
to thread's FPU defaults: the value to initialise FSCR to at program
startup, the FCSR r/w mask and the contents of FIR in full FPU
emulation, removing a regression introduced with 9b26616c [MIPS: Respect
the ISA level in FCSR handling] and f6843626 [MIPS: math-emu: Set FIR
feature flags for full emulation].
Use `boot_cpu_data' to obtain the data from, following the approach that
`cpu_has_*' macros take and avoiding the call to `smp_processor_id' made
in the reference to `current_cpu_data'. The contents of FSCR have to be
consistent across processors in an SMP system, the settings there must
not change as a thread is migrated across processors. And the contents
of FIR are guaranteed to be consistent in FPU emulation, by definition.

parisc,metag: Fix crashes due to stack randomization on stack-grows-upwards architectures
On architectures where the stack grows upwards (CONFIG_STACK_GROWSUP=y,
currently parisc and metag only) stack randomization sometimes leads to crashes
when the stack ulimit is set to lower values than STACK_RND_MASK (which is 8 MB
by default if not defined in arch-specific headers).
The problem is, that when the stack vm_area_struct is set up in fs/exec.c, the
additional space needed for the stack randomization (as defined by the value of
STACK_RND_MASK) was not taken into account yet and as such, when the stack
randomization code added a random offset to the stack start, the stack
effectively got smaller than what the user defined via rlimit_max(RLIMIT_STACK)
which then sometimes leads to out-of-stack situations and crashes.
This patch fixes it by adding the maximum possible amount of memory (based on
STACK_RND_MASK) which theoretically could be added by the stack randomization
code to the initial stack size. That way, the user-defined stack size is always
guaranteed to be at minimum what is defined via rlimit_max(RLIMIT_STACK).
This bug is currently not visible on the metag architecture, because on metag
STACK_RND_MASK is defined to 0 which effectively disables stack randomization.
The changes to fs/exec.c are inside an "#ifdef CONFIG_STACK_GROWSUP"
section, so it does not affect other platformws beside those where the
stack grows upwards (parisc and metag).

ASoC: rt5645: improve headphone depop function
We add a calibration function and call it at the beginning of i2c_probe.
The calibration value will be kept until codec is shutdown. We will reset
the codec after the calibration is finished. So, we set cache_bypass in
the calibration function. The benefit is we can shorter the delay time
in headphone depop.
We also change the register setting in the depop sequence which will
reduce the pop noise in headphone playback.

rcutorture: Allow repetition factors in Kconfig-fragment lists
Although it is currently possible to run the same test in parallel,
'--config "TINY01 TINY01 TINY01"' can get a bit verbose, especially
if you want to run 48 instances of TINY01 in parallel. This commit
therefore allows prefixing the Kconfig fragment with a repeat count,
for example, '--config "48*TINY01"' to run 48 instances in parallel.
At least assuming that you have 48 CPUs and also gave '--cpus 48'.

rcutorture: Test SRCU cleanup code path
The current rcutorture testing does not do any cleanup operations.
This works because the srcu_struct is statically allocated, but it
does represent a memory leak of the associated dynamically allocated
->per_cpu_ref per-CPU variables. However, rcutorture currently uses
a statically allocated srcu_struct, which cannot legally be passed to
cleanup_srcu_struct(). Therefore, this commit adds a second form
of srcu (called srcud) that dynamically allocates and frees the
associated per-CPU variables. This commit also adds a ->cleanup()
member to rcu_torture_ops that is invoked at the end of the test,
after ->cb_barriers(). This ->cleanup() pointer is NULL for all
existing tests, and thus only used for scrud. Finally, the SRCU-P
torture-test configuration selects scrud instead of srcu, with SRCU-N
continuing to use srcu, thereby testing both static and dynamic
srcu_struct structures.

rcu: Correctly handle non-empty Tiny RCU callback list with none ready
If, at the time __rcu_process_callbacks() is invoked, there are callbacks
in Tiny RCU's callback list, but none of them are ready to be invoked,
the current list-management code will knit the non-ready callbacks out
of the list. This can result in hangs and possibly worse. This commit
therefore inserts a check for there being no callbacks that can be
invoked immediately.
This bug is unlikely to occur -- you have to get a new callback between
the time rcu_sched_qs() or rcu_bh_qs() was called, but before we get to
__rcu_process_callbacks(). It was detected by the addition of RCU-bh
testing to rcutorture, which in turn was instigated by Iftekhar Ahmed's
mutation testing. Although this bug was made much more likely by
915e8a4fe45e (rcu: Remove fastpath from __rcu_process_callbacks()), this
did not cause the bug, but rather made it much more probable. That
said, it takes more than 40 hours of rcutorture testing, on average,
for this bug to appear, so this fix cannot be considered an emergency.

rcu: Further shrink Tiny RCU by making empty functions static inlines
The Tiny RCU counterparts to rcu_idle_enter(), rcu_idle_exit(),
rcu_irq_enter(), and rcu_irq_exit() are empty functions, but each
has EXPORT_SYMBOL_GPL(), which, in kernels built with module support,
needlessly consumes some memory. This commit therefore moves these
functions to static inlines in rcutiny.h, removing the need for
exports.
This won't affect the size of the tiniest kernels, which are likely
built without module support, but might help semi-tiny kernels that
might include module support.

rtc: ds1307: Enable the mcp794xx alarm after programming time
Alarm interrupt enable register is at offset 0x7, while the time
registers for the alarm follow that. When we program Alarm interrupt
enable prior to programming the time, it is possible that previous
time value could be close or match at the time of alarm enable
resulting in interrupt trigger which is unexpected (and does not match
the time we expect it to trigger).
To prevent this scenario from occuring, program the ALM0_EN bit only
after the alarm time is appropriately programmed.
Ofcourse, I2C programming is non-atomic, so there are loopholes where
the interrupt wont trigger if the time requested is in the past at
the time of programming the ALM0_EN bit. However, we will not have
unexpected interrupts while the time is programmed after the interrupt
are enabled.

ahci: Add support for Cavium's ThunderX host controller
This patch adds support for Cavium's ThunderX host controller. The
controller resides on the SoC and is a AHCI compatible SATA controller
with one port, compliant with Serial ATA 3.1 and AHCI Revision 1.31.
There can exists multiple SATA controllers on the SoC.
The controller depends on MSI-X support since the PCI ECAM controller
on the SoC does not implement MSI nor lagacy intx interrupt support.
Thus, during device initialization, if MSI fails MSI-X will be used to
enable the device's interrupts.
The controller uses non-standard BAR0 for its register range. The
already existing device lookup (vendor and device id) that is already
implemented for other host controllers is used to change the PCI BAR.

ahci: Add generic MSI-X support for single interrupts to SATA PCI driver
This patch adds generic MSI-X support for single interrupts to the
SATA PCI driver. MSI-X support is needed for host controller that only
have MSI-X support implemented, but no MSI or intx. This patch only
adds support for single interrupts, multiple per-port MSI-X interrupts
are not yet implemented.
The new implementation still initializes MSIs first. Only if that
fails, the code tries to enable MSI-X. If that fails too, setup is
continued with intx interrupts.
To not break other chips by this generic code change, there are the
following precautions:
* Interrupt ranges are not enabled at all.
* Only single interrupt mode is enabled for msix cap devices. Thus,
only one interrupt will be setup.
* During the discussion with Tejun we agreed to change the init
sequence from msix-msi-intx to msi-msix-intx. Thus, if a device
offers msi and init does not fail, the msix init code will not be
executed. This is equivalent to current code.
With this, the code only setups single mode msix as a last resort if
msi fails. No interrupt range is enabled at all. Only one interrupt
will be enabled.
tj: comment edits.
Changes of the patch series:
v5:
* updated patch subject that the patch only implements single IRQ
* moved Cavium specific code to a separate patch
* detect Cavium ThunderX device with PCI_CLASS_STORAGE_SATA_AHCI
instead of vendor/dev id
* added more comments to the code
* enable single msix support for all kind of devices (removing strict
check)
* rebased onto update libata/for-4.2 with patch 1, 2 applied
v4:
* removed implementation of ahci_init_intx()
* improved patch descriptions
* rebased onto libata/for-4.2
v3:
* store irq number in struct ahci_host_priv
* change initialization order from msix-msi-intx to msi-msix-intx
* improve comments in ahci_init_msix()
* improve error message in ahci_init_msix()
* do not enable MSI-X if MSI is actively disabled for the device

module: relocate module_init from init.h to module.h
Modular users will always be users of init functionality, but
users of init functionality are not necessarily always modules.
Hence any functionality like module_init and module_exit would
be more at home in the module.h file. And module.h should
explicitly include init.h to make the dependency clear.
We've already done all the legwork needed to ensure that this
move does not cause any build regressions due to implicit
header file include assumptions about where module_init lives.

As of commit 34b1252bd91851f77f89fbb6829a04efad900f41 ("MIPS:
Cobalt: Do not build MTD platform device registration code as module.")
this file became built-in instead of modular. So we should also
stop using module_init as an alias for __initcall as that can be
rather misleading.
Fix this up now, so that we can relocate module_init from
init.h into module.h in the future. If we don't do this, we'd
have to add module.h to obviously non-modular code, and that
would be a worse thing.
Direct use of __initcall is discouraged, vs prioritized ones.
Use of device_initcall is consistent with what __initcall
maps onto, and hence does not change the init order, making the
impact of this change zero.

drivers/leds: don't use module_init in non-modular leds-cobalt-raq.c
This file is built for a bool Kconfig variable, and hence this
code is either present or absent. It currently can never be
modular, so using module_init as an alias for __initcall can be
somewhat misleading.
Fix this up now, so that we can relocate module_init from
init.h into module.h in the future. If we don't do this, we'd
have to add module.h to obviously non-modular code, and that
would be a worse thing.
Note that direct use of __initcall is discouraged, vs. one
of the priority categorized subgroups. As __initcall gets
mapped onto device_initcall, our use of device_initcall
directly in this change means that the runtime impact is
zero -- it will remain at level 6 in initcall ordering.
And since it can't be modular, we remove all the __exitcall
stuff related to module_exit() -- it is dead code that won't
ever be executed.

x86: replace __init_or_module with __init in non-modular vsmp_64.c
The __init_or_module is from commit 05e12e1c4c09cd35ac9f4e6af1e
("x86: fix 27-rc crash on vsmp due to paravirt during module load").
But as of commit 70511134f61bd6e5eed19f767381f9fb3e762d49
("Revert "x86: don't compile vsmp_64 for 32bit") this file became
obj-y and hence is now only for built-in. That makes any
"_or_module" support no longer necessary.
We need to distinguish between the two in order to do some header
reorganization between init.h and module.h and we don't want to
be including module.h in non-modular code.

platform_device: better support builtin boilerplate avoidance
We have macros that help reduce the boilerplate for modules
that register with no extra init/exit complexity other than the
most standard use case. However we see an increasing number of
non-modular drivers using these modular_driver() type register
functions.
There are several downsides to this:
1) The code can appear modular to a reader of the code, and they
won't know if the code really is modular without checking the
Makefile and Kconfig to see if compilation is governed by a
bool or tristate.
2) Coders of drivers may be tempted to code up an __exit function
that is never used, just in order to satisfy the required three
args of the modular registration function.
3) Non-modular code ends up including the <module.h> which increases
CPP overhead that they don't need.
4) It hinders us from performing better separation of the module
init code and the generic init code.
Here we introduce similar macros, with the mapping from module_driver
to builtin_driver and similar, so that simple changes of:
module_platform_driver() ---> builtin_platform_driver()
module_platform_driver_probe() ---> builtin_platform_driver_probe().
can help us avoid #3 above, without having to code up the same
__init functions and device_initcall() boilerplate.
For non modular code, module_init becomes __initcall. But direct use
of __initcall is discouraged, vs. one of the priority categorized
subgroups. As __initcall gets mapped onto device_initcall, our
use of device_initcall directly in this change means that the
runtime impact is zero -- drivers will remain at level 6 in the
initcall ordering.

x86: perf_event_intel_pt.c: use arch_initcall to hook in enabling
This was using module_init, but the current Kconfig situation is
as follows:
In arch/x86/kernel/cpu/Makefile:
obj-$(CONFIG_CPU_SUP_INTEL) += perf_event_intel_pt.o perf_event_intel_bts.o
and in arch/x86/Kconfig.cpu:
config CPU_SUP_INTEL
default y
bool "Support Intel processors" if PROCESSOR_SELECT
So currently, the end user can not build this code into a module.
If in the future, there is desire for this to be modular, then
it can be changed to include <linux/module.h> and use module_init.
But currently, in the non-modular case, a module_init becomes a
device_initcall. But this really isn't a device, so we should
choose a more appropriate initcall bucket to put it in.
The obvious choice here seems to be arch_initcall, but that does
make it earlier than it was currently through device_initcall.
As long as perf_pmu_register() is functional, we should be OK.

seems to make sense for netfilter code) will thus change this
registration from level 6-device to level 4-subsys (i.e. slightly
earlier). However no observable impact of that small difference
has been observed during testing, or is expected. (i.e. the
location of the netfilter messages in dmesg remains unchanged
with respect to all the other surrounding messages.)
As for the module_exit, rather than replace it with __exitcall,
we simply remove it, since it appears only UML does anything
with those, and even for UML, there is no relevant cleanup
to be done here.

fs/notify: don't use module_init for non-modular inotify_user code
The INOTIFY_USER option is bool, and hence this code is either
present or absent. It will never be modular, so using
module_init as an alias for __initcall is rather misleading.
Fix this up now, so that we can relocate module_init from
init.h into module.h in the future. If we don't do this, we'd
have to add module.h to obviously non-modular code, and that
would be a worse thing.
Note that direct use of __initcall is discouraged, vs. one

mapped onto device_initcall, our use of fs_initcall (which
makes sense for fs code) will thus change this registration

However no observable impact of that small difference has
been observed during testing, or is expected.

mm: replace module_init usages with subsys_initcall in nommu.c
Compiling some arm/m68k configs with "# CONFIG_MMU is not set" reveals
two more instances of module_init being used for code that can't
possibly be modular, as CONFIG_MMU is either on or off.
We replace them with subsys_initcall as per what was done in other
mmu-enabled code.
Note that direct use of __initcall is discouraged, vs. one of the
priority categorized subgroups. As __initcall gets mapped onto
device_initcall, our use of subsys_initcall (which makes sense for these
files) will thus change this registration from level 6-device to level
4-subsys (i.e. slightly earlier).
One might think that core_initcall (l2) or postcore_initcall (l3) would
be more appropriate for anything in mm/ but if we look at the actual init
functions themselves, we see they are just sysctl setup stuff, and
hence the choice of subsys_initcall (l4) seems reasonable. At the same
time it minimizes the risk of changing the priority too drastically all
at once. We can adjust further in the future.
Also, a couple instances of missing ";" at EOL are fixed.

tty/metag_da: Avoid module_init/module_exit in non-modular code
The metag_da TTY driver can't get built as a module at the moment, but
it still uses module_init() and module_exit(). Those macros are moving
to module.h which isn't included by metag_da.c, which will result in the
following build warnings (remarkably no build errors) and an apparent
failure to boot as the TTY driver won't be loaded.
drivers/tty/metag_da.c:660: warning: data definition has no type or storage class
drivers/tty/metag_da.c:660: warning: type defaults to ‘int’ in declaration of ‘module_init’
drivers/tty/metag_da.c:660: warning: parameter names (without types) in function declaration
drivers/tty/metag_da.c:661: warning: data definition has no type or storage class
drivers/tty/metag_da.c:661: warning: type defaults to ‘int’ in declaration of ‘module_exit’

drivers/tty/metag_da.c:572: warning: ‘dashtty_init’ defined but not used
drivers/tty/metag_da.c:645: warning: ‘dashtty_exit’ defined but not used
drivers/tty/metag_da.c In function ‘dash_console_write’:
drivers/tty/metag_da.c:670 : warning: passing argument 4 of ‘chancall’ discards qualifiers from pointer target type
Instead of just adding the module.h include, now would be a good time to
remove the use of these macros, replacing the module_init with
device_initcall, and removing the exit function altogether since it
isn't needed. If module support is added later the code can always be
resurrected.

drivers/cpufreq: include <module.h> for modular exynos-cpufreq.c code
This file is built off of a tristate Kconfig option ("ARM_EXYNOS_CPUFREQ")
and also contains modular function calls so it should explicitly include
module.h to avoid compile breakage during pending header shuffles.

crypto/asymmetric_keys: pkcs7_key_type needs module.h
This driver builds off of the tristate CONFIG_PKCS7_TEST_KEY and calls
module_init and module_exit. So it should explicitly include module.h
to avoid compile breakage during header shuffles done in the future.

sh: mach-highlander/psw.c is tristate and should use module.h
This file is controlled by a tristate Kconfig option, and hence
needs to include module.h so that it can get module_init() once
we relocate it from init.h into module.h in the future.
Note that module_exit() appears to be missing from the driver, so
it is questionable whether it would actually work for a removal
and reload cycle if it was configured for a modular build.

Debug interrupts can be taken during regular program or a standard
interrupt, the EA of the instruction causing the interrupt will be
kept in DSRR0.
Kernel will check if this value is between [interrupt_base_book3e,
__end_interrupts].
However, when the kernel build with CONFIG_RELOCATABLE, it can't get
EA of those lables by LOAD_REG_IMMEDIATE(r14,interrupt_base_book3e)
and LOAD_REG_IMMEDIATE(r15,__end_interrupts),then it cases problems
later.
At the same time, r2(toc) are not usable here, so LOAD_REG_ADDR()
dosen't work neither. So we use the *name@got* to get the EV of two
lables directly.
This patch can fix the problem and remove the oops when we gdb a
program with single-step.
Test programs test.c shows as follows:
#include <fcntl.h>
#include <stdio.h>
int main(int argc, char *argv[])
{
if (access("/proc/sys/kernel/perf_event_paranoid", F_OK) == -1)
printf("Kernel doesn't have perf_event support\n");
}
Steps to reproduce the bug, for example:
1) ./gdb ./test
2) (gdb) b access
3) (gdb) r
4) (gdb) s
Then will trigger the oops, it looks like:
(gdb) s

Since extent_writepage_io() failed, we need to call btrfs_mark_ordered_io_finished() to cleanup the submitted range. But we will call btrfs_mark_ordered_io_finished() for submitted range too, causing double accounting. 2) Partially created ordered extents We cal also fail at writepage_delalloc(), which will stop creating new ordered extents if it hit any error from btrfs_run_delalloc_range(). In that case, we will call btrfs_mark_ordered_io_finished() for ranges where there is no ordered extent at all. Both bugs are only affecting sector size < page size cases. [FIX] - Introduce a new member btrfs_bio_ctrl::last_submitted This will trace the last sector submitted through extent_writepage_io(). So for the above extent_writepage() case, we will know exactly which sectors are submitted and should not do the ordered extent accounting. - Clear the submit_bitmap for ranges where no ordered extent is created So if btrfs_run_delalloc_range() failed for a range, it will be not cleaned up. - Introduce a helper cleanup_ordered_extents() This will do a sector-by-sector cleanup with btrfs_bio_ctrl::last_submitted and btrfs_bio_ctrl::submit_bitmap into consideartion. Using @last_submitted is to avoid double accounting on the submitted ranges. Meanwhile using @submit_bitmap is to avoid touching ranges going through compression. cc: stable@vger.kernel.org # 5.15+ Signed-off-by: Qu Wenruo <wqu@suse.com>

I may be wrong with that interpretation... Sometimes this lead to the accelerometer not working after resume. In order to prevent spurious irqs during the standby/resume cycle, explicitly turn off the device and irq during suspend, and resume by hand when the system resumes.

It is possible to see that fsck.hfsplus detected not
erased and unused node for the case of extents overflow file.
The HFS+ logic has special method that defines if the node
should be erased:
bool hfs_bnode_need_zeroout(struct hfs_btree *tree)
{
struct super_block *sb = tree->inode->i_sb;
struct hfsplus_sb_info *sbi = HFSPLUS_SB(sb);
const u32 volume_attr = be32_to_cpu(sbi->s_vhdr->attributes);
return tree->cnid == HFSPLUS_CAT_CNID &&
volume_attr & HFSPLUS_VOL_UNUSED_NODE_FIX;
}
However, it is possible to see that this method works
only for the case of catalog file. But debugging of the issue
has shown that HFSPLUS_VOL_UNUSED_NODE_FIX attribute has been
requested for the extents overflow file too:
catalog file
kernel: hfsplus: node 4, num_recs 0, flags 0x10
kernel: hfsplus: tree->cnid 4, volume_attr 0x80000800
extents overflow file
kernel: hfsplus: node 1, num_recs 0, flags 0x10
kernel: hfsplus: tree->cnid 3, volume_attr 0x80000800
This patch modifies the hfs_bnode_need_zeroout() by checking
only volume_attr but not the b-tree ID because node zeroing
can be requested for all HFS+ b-tree types.

It is possible to see that fsck.hfsplus detected not
erased and unused node for the case of extents overflow file.
The HFS+ logic has special method that defines if the node
should be erased:
bool hfs_bnode_need_zeroout(struct hfs_btree *tree)
{
struct super_block *sb = tree->inode->i_sb;
struct hfsplus_sb_info *sbi = HFSPLUS_SB(sb);
const u32 volume_attr = be32_to_cpu(sbi->s_vhdr->attributes);
return tree->cnid == HFSPLUS_CAT_CNID &&
volume_attr & HFSPLUS_VOL_UNUSED_NODE_FIX;
}
However, it is possible to see that this method works
only for the case of catalog file. But debugging of the issue
has shown that HFSPLUS_VOL_UNUSED_NODE_FIX attribute has been
requested for the extents overflow file too:
catalog file
kernel: hfsplus: node 4, num_recs 0, flags 0x10
kernel: hfsplus: tree->cnid 4, volume_attr 0x80000800
extents overflow file
kernel: hfsplus: node 1, num_recs 0, flags 0x10
kernel: hfsplus: tree->cnid 3, volume_attr 0x80000800
This patch modifies the hfs_bnode_need_zeroout() by checking
only volume_attr but not the b-tree ID because node zeroing
can be requested for all HFS+ b-tree types.

[ Upstream commit ed490f3 ] The xfstests' test-case generic/070 leaves HFS+ volume in corrupted state: sudo ./check generic/070 FSTYP -- hfsplus PLATFORM -- Linux/x86_64 hfsplus-testing-0001 6.17.0-rc1+ #4 SMP PREEMPT_DYNAMIC Wed Oct 1 15:02:44 PDT 2025 MKFS_OPTIONS -- /dev/loop51 MOUNT_OPTIONS -- /dev/loop51 /mnt/scratch generic/070 _check_generic_filesystem: filesystem on /dev/loop50 is inconsistent (see xfstests-dev/results//generic/070.full for details) Ran: generic/070 Failures: generic/070 Failed 1 of 1 tests sudo fsck.hfsplus -d /dev/loop50 ** /dev/loop50 Using cacheBlockSize=32K cacheTotalBlock=1024 cacheSize=32768K.

The volume name is test ** Checking extents overflow file. ** Checking catalog file. ** Checking multi-linked files. ** Checking catalog hierarchy. ** Checking extended attributes file. ** Checking volume bitmap. ** Checking volume information. ** The volume test was repaired successfully. It is possible to see that fsck.hfsplus detected not erased and unused node for the case of extents overflow file. The HFS+ logic has special method that defines if the node should be erased: bool hfs_bnode_need_zeroout(struct hfs_btree *tree) { struct super_block *sb = tree->inode->i_sb; struct hfsplus_sb_info *sbi = HFSPLUS_SB(sb); const u32 volume_attr = be32_to_cpu(sbi->s_vhdr->attributes); return tree->cnid == HFSPLUS_CAT_CNID && volume_attr & HFSPLUS_VOL_UNUSED_NODE_FIX; } However, it is possible to see that this method works only for the case of catalog file. But debugging of the issue has shown that HFSPLUS_VOL_UNUSED_NODE_FIX attribute has been requested for the extents overflow file too: catalog file kernel: hfsplus: node 4, num_recs 0, flags 0x10 kernel: hfsplus: tree->cnid 4, volume_attr 0x80000800 extents overflow file kernel: hfsplus: node 1, num_recs 0, flags 0x10 kernel: hfsplus: tree->cnid 3, volume_attr 0x80000800 This patch modifies the hfs_bnode_need_zeroout() by checking only volume_attr but not the b-tree ID because node zeroing can be requested for all HFS+ b-tree types. sudo ./check generic/070 FSTYP -- hfsplus PLATFORM -- Linux/x86_64 hfsplus-testing-0001 6.18.0-rc3+ torvalds#79 SMP PREEMPT_DYNAMIC Fri Oct 31 16:07:42 PDT 2025 MKFS_OPTIONS -- /dev/loop51 MOUNT_OPTIONS -- /dev/loop51 /mnt/scratch generic/070 33s ... 34s Ran: generic/070 Passed all 1 tests Signed-off-by: Viacheslav Dubeyko <slava@dubeyko.com> cc: John Paul Adrian Glaubitz <glaubitz@physik.fu-berlin.de> cc: Yangtao Li <frank.li@vivo.com> cc: linux-fsdevel@vger.kernel.org Link: https://lore.kernel.org/r/20251101001229.247432-1-slava@dubeyko.com Signed-off-by: Viacheslav Dubeyko <slava@dubeyko.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
