Hi @zhouhanjiang! Thanks for your contribution to the Linux kernel! Linux kernel development happens on mailing lists, rather than on GitHub - this GitHub repository is a read-only mirror that isn't used for accepting contributions. So that your change can become part of Linux, please email it to us as a patch. Sending patches isn't quite as simple as sending a pull request, but fortunately it is a well documented process. Here's what to do:
How do I format my contribution?The Linux kernel community is notoriously picky about how contributions are formatted and sent. Fortunately, they have documented their expectations. Firstly, all contributions need to be formatted as patches. A patch is a plain text document showing the change you want to make to the code, and documenting why it is a good idea. You can create patches with Secondly, patches need 'commit messages', which is the human-friendly documentation explaining what the change is and why it's necessary. Thirdly, changes have some technical requirements. There is a Linux kernel coding style, and there are licensing requirements you need to comply with. Both of these are documented in the Submitting Patches documentation that is part of the kernel. Note that you will almost certainly have to modify your existing git commits to satisfy these requirements. Don't worry: there are many guides on the internet for doing this. Who do I send my contribution to?The Linux kernel is composed of a number of subsystems. These subsystems are maintained by different people, and have different mailing lists where they discuss proposed changes. If you don't already know what subsystem your change belongs to, the
Make sure that your list of recipients includes a mailing list. If you can't find a more specific mailing list, then LKML - the Linux Kernel Mailing List - is the place to send your patches. It's not usually necessary to subscribe to the mailing list before you send the patches, but if you're interested in kernel development, subscribing to a subsystem mailing list is a good idea. (At this point, you probably don't need to subscribe to LKML - it is a very high traffic list with about a thousand messages per day, which is often not useful for beginners.) How do I send my contribution?Use For more information about using How do I get help if I'm stuck?Firstly, don't get discouraged! There are an enormous number of resources on the internet, and many kernel developers who would like to see you succeed. Many issues - especially about how to use certain tools - can be resolved by using your favourite internet search engine. If you can't find an answer, there are a few places you can turn:
If you get really, really stuck, you could try the owners of this bot, @daxtens and @ajdlinux. Please be aware that we do have full-time jobs, so we are almost certainly the slowest way to get answers! I sent my patch - now what?You wait. You can check that your email has been received by checking the mailing list archives for the mailing list you sent your patch to. Messages may not be received instantly, so be patient. Kernel developers are generally very busy people, so it may take a few weeks before your patch is looked at. Then, you keep waiting. Three things may happen:

platform/x86: intel_turbo_max_3: make it explicitly non-modular
The Kconfig currently controlling compilation of this code is:
drivers/platform/x86/Kconfig:config INTEL_TURBO_MAX_3
drivers/platform/x86/Kconfig: bool "Intel Turbo Boost Max Technology 3.0 enumeration driver"
...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modular infrastructure use, so that
when reading the driver there is no doubt it is builtin-only.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.
We do uncover some implicit includes during build coverage that
were hidden behind the module.h which pulls in a lot of dependants.

leds: class: Add new optional brightness_hw_changed attribute
Some LEDs may have their brightness level changed autonomously
(outside of kernel control) by hardware / firmware. This commit
adds support for an optional brightness_hw_changed attribute to
signal such changes to userspace (if a driver can detect them):
What: /sys/class/leds/<led>/brightness_hw_changed
Date: January 2017
KernelVersion: 4.11
Description:
Last hardware set brightness level for this LED. Some LEDs
may be changed autonomously by hardware/firmware. Only LEDs
where this happens and the driver can detect this, will
have this file.
This file supports poll() to detect when the hardware
changes the brightness.
Reading this file will return the last brightness level set
by the hardware, this may be different from the current
brightness.
Drivers which want to support this, simply add LED_BRIGHT_HW_CHANGED to
their flags field and call led_classdev_notify_brightness_hw_changed()
with the hardware set brightness when they detect a hardware / firmware
triggered brightness change.

rename the lm_status to app_status. And also the app_mask is the bit
mask which specifically indicate which bits are going to be changed.

platform/x86: asus-wireless: Use per-HID HSWC parameters
Some Asus machines use 0x4/0x5 as their LED on/off values, while others
use 0x0/0x1, as shown in the DSDT excerpts below. Luckily it seems this
behavior is tied to different HIDs, after looking at 44 DSDTs from
different Asus models.
Another small difference is that a few of them call GWBL instead of
OWGS, and SWBL instead of OWGD. That does not seem to make a difference
for asus-wireless, and is additional reasoning to not try to call these
methods directly.

lib: update LZ4 compressor module
Patch series "Update LZ4 compressor module", v7.
This patchset updates the LZ4 compression module to a version based on
LZ4 v1.7.3 allowing to use the fast compression algorithm aka LZ4 fast
which provides an "acceleration" parameter as a tradeoff between high
compression ratio and high compression speed.
We want to use LZ4 fast in order to support compression in lustre and
(mostly, based on that) investigate data reduction techniques in behalf
of storage systems.
Also, it will be useful for other users of LZ4 compression, as with LZ4
fast it is possible to enable applications to use fast and/or high
compression depending on the usecase. For instance, ZRAM is offering a
LZ4 backend and could benefit from an updated LZ4 in the kernel.
LZ4 homepage: http://www.lz4.org/
LZ4 source repository: https://github.com/lz4/lz4 Source version: 1.7.3
Benchmark (taken from [1], Core i5-4300U @1.9GHz):

[PATCH 4/5] fs/pstore: fs/squashfs: Change usage of LZ4 to work with new LZ4 version
[PATCH 5/5] lib/lz4: Remove back-compat wrappers
This patch (of 5):
Update the LZ4 kernel module to LZ4 v1.7.3 by Yann Collet. The kernel
module is inspired by the previous work by Chanho Min. The updated LZ4
module will not break existing code since the patchset contains
appropriate changes.
API changes:
New method LZ4_compress_fast which differs from the variant available in
kernel by the new acceleration parameter, allowing to trade compression
ratio for more compression speed and vice versa.
LZ4_decompress_fast is the respective decompression method, featuring a
very fast decoder (multiple GB/s per core), able to reach RAM speed in
multi-core systems. The decompressor allows to decompress data
compressed with LZ4 fast as well as the LZ4 HC (high compression)
algorithm.
Also the useful functions LZ4_decompress_safe_partial and
LZ4_compress_destsize were added. The latter reverses the logic by
trying to compress as much data as possible from source to dest while
the former aims to decompress partial blocks of data.
A bunch of streaming functions were also added which allow
compressig/decompressing data in multiple steps (so called "streaming
mode").
The methods lz4_compress and lz4_decompress_unknownoutputsize are now
known as LZ4_compress_default respectivley LZ4_decompress_safe. The old
methods will be removed since there's no callers left in the code.

lib/test_sort.c: make it explicitly non-modular
The Kconfig currently controlling compilation of this code is:
lib/Kconfig.debug:config TEST_SORT
lib/Kconfig.debug: bool "Array-based sort test"
...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modular infrastructure use, so that
when reading the code there is no doubt it is builtin-only.
Since module_init translates to device_initcall in the non-modular case,
the init ordering becomes slightly earlier when we change it to use
subsys_initcall as done here. However, since it is a self contained
test, this shouldn't be an issue and subsys_initcall seems like a better
fit for this particular case.
We also delete the MODULE_LICENSE tag since that information is now
contained at the top of the file in the comments.

linux/kernel.h: fix DIV_ROUND_CLOSEST to support negative divisors
While working on a thermal driver I encounter a scenario where the
divisor could be negative, instead of adding local code to handle this I
though I first try to add support for this in DIV_ROUND_CLOSEST.
Add support to DIV_ROUND_CLOSEST for negative divisors if both dividend
and divisor variable types are signed. This should not alter current
behavior for users of the macro as previously negative divisors where
not supported.
Before:
DIV_ROUND_CLOSEST( 59, 4) = 15
DIV_ROUND_CLOSEST( 59, -4) = -14
DIV_ROUND_CLOSEST( -59, 4) = -15
DIV_ROUND_CLOSEST( -59, -4) = 14
After:
DIV_ROUND_CLOSEST( 59, 4) = 15
DIV_ROUND_CLOSEST( 59, -4) = -15
DIV_ROUND_CLOSEST( -59, 4) = -15
DIV_ROUND_CLOSEST( -59, -4) = 15

lib/find_bit.c: micro-optimise find_next_*_bit
This saves 32 bytes on my x86-64 build, mostly due to alignment
considerations and sharing more code between find_next_bit and
find_next_zero_bit, but it does save a couple of instructions.
There's really two parts to this commit:
- First, the first half of the test: (!nbits || start >= nbits) is
trivially a subset of the second half, since nbits and start are both
unsigned
- Second, while looking at the disassembly, I noticed that GCC was
predicting the branch taken. Since this is a failure case, it's
clearly the less likely of the two branches, so add an unlikely() to
override GCC's heuristics.

bug: switch data corruption check to __must_check
The CHECK_DATA_CORRUPTION() macro was designed to have callers do
something meaningful/protective on failure. However, using "return
false" in the macro too strictly limits the design patterns of callers.
Instead, let callers handle the logic test directly, but make sure that
the result IS checked by forcing __must_check (which appears to not be
able to be used directly on macro expressions).

procfs: use an enum for possible hidepid values
Previously, the hidepid parameter was checked by comparing literal
integers 0, 1, 2. Let's add a proper enum for this, to make the
checking more expressive:
0 → HIDEPID_OFF
1 → HIDEPID_NO_ACCESS
2 → HIDEPID_INVISIBLE
This changes the internal labelling only, the userspace-facing interface
remains unmodified, and still works with literal integers 0, 1, 2.
No functional changes.

kasan: add memcg kmem_cache test
Make a kasan test which uses a SLAB_ACCOUNT slab cache. If the test is
run within a non default memcg, then it uncovers the bug fixed by
"kasan: drain quarantine of memcg slab objects"[1].
If run without fix [1] it shows "Slab cache still has objects", and the
kmem_cache structure is leaked.
Here's an unpatched kernel test:
$ dmesg -c > /dev/null
$ mkdir /sys/fs/cgroup/memory/test
$ echo $$ > /sys/fs/cgroup/memory/test/tasks
$ modprobe test_kasan 2> /dev/null
$ dmesg | grep -B1 still
[ 123.456789] kasan test: memcg_accounted_kmem_cache allocate memcg accounted object
[ 124.456789] kmem_cache_destroy test_cache: Slab cache still has objects
Kernels with fix [1] don't have the "Slab cache still has objects"
warning or the underlying leak.
The new test runs and passes in the default (root) memcg, though in the
root memcg it won't uncover the problem fixed by [1].

kasan: drain quarantine of memcg slab objects
Per memcg slab accounting and kasan have a problem with kmem_cache
destruction.
- kmem_cache_create() allocates a kmem_cache, which is used for
allocations from processes running in root (top) memcg.
- Processes running in non root memcg and allocating with either
__GFP_ACCOUNT or from a SLAB_ACCOUNT cache use a per memcg
kmem_cache.
- Kasan catches use-after-free by having kfree() and kmem_cache_free()
defer freeing of objects. Objects are placed in a quarantine.
- kmem_cache_destroy() destroys root and non root kmem_caches. It takes
care to drain the quarantine of objects from the root memcg's
kmem_cache, but ignores objects associated with non root memcg. This
causes leaks because quarantined per memcg objects refer to per memcg
kmem cache being destroyed.
To see the problem:
1) create a slab cache with kmem_cache_create(,,,SLAB_ACCOUNT,)
2) from non root memcg, allocate and free a few objects from cache
3) dispose of the cache with kmem_cache_destroy() kmem_cache_destroy()
will trigger a "Slab cache still has objects" warning indicating
that the per memcg kmem_cache structure was leaked.
Fix the leak by draining kasan quarantined objects allocated from non
root memcg.
Racing memcg deletion is tricky, but handled. kmem_cache_destroy() =>
shutdown_memcg_caches() => __shutdown_memcg_cache() => shutdown_cache()
flushes per memcg quarantined objects, even if that memcg has been
rmdir'd and gone through memcg_deactivate_kmem_caches().
This leak only affects destroyed SLAB_ACCOUNT kmem caches when kasan is
enabled. So I don't think it's worth patching stable kernels.

memory-hotplug: use dev_online for memhp_auto_online
Commit 31bc3858ea3e ("add automatic onlining policy for the newly added
memory") provides the capability to have added memory automatically
onlined during add, but this appears to be slightly broken.
The current implementation uses walk_memory_range() to call
online_memory_block, which uses memory_block_change_state() to online
the memory. Instead, we should be calling device_online() for the
memory block in online_memory_block(). This would online the memory
(the memory bus online routine memory_subsys_online() called from
device_online calls memory_block_change_state()) and properly update the
device struct offline flag.
As a result of the current implementation, attempting to remove a memory
block after adding it using auto online fails. This is because doing a
remove, for instance
echo offline > /sys/devices/system/memory/memoryXXX/state
uses device_offline() which checks the dev->offline flag.

mm: do not access page->mapping directly on page_endio
With rw_page, page_endio is used for completing IO on a page and it
propagates write error to the address space if the IO fails. The
problem is it accesses page->mapping directly which might be okay for
file-backed pages but it shouldn't for anonymous page. Otherwise, it
can corrupt one of field from anon_vma under us and system goes panic
randomly.
swap_writepage
bdev_writepage
ops->rw_page
I encountered the BUG during developing new zram feature and it was
really hard to figure it out because it made random crash, somtime
mmap_sem lockdep, sometime other places where places never related to
zram/zsmalloc, and not reproducible with some configuration.
When I consider how that bug is subtle and people do fast-swap test with
brd, it's worth to add stable mark, I think.

mm/zsmalloc: remove redundant SetPagePrivate2 in create_page_chain
We had used page->lru to link the component pages (except the first
page) of a zspage, and used INIT_LIST_HEAD(&page->lru) to init it.
Therefore, to get the last page's next page, which is NULL, we had to
use page flag PG_Private_2 to identify it.
But now, we use page->freelist to link all of the pages in zspage and
init the page->freelist as NULL for last page, so no need to use
PG_Private_2 anymore.
This remove redundant SetPagePrivate2 in create_page_chain and
ClearPagePrivate2 in reset_page(). Save a few cycles for migration of
zsmalloc page :)

mm: vmpressure: fix sending wrong events on underflow
At the end of a window period, if the reclaimed pages is greater than
scanned, an unsigned underflow can result in a huge pressure value and
thus a critical event. Reclaimed pages is found to go higher than
scanned because of the addition of reclaimed slab pages to reclaimed in
shrink_node without a corresponding increment to scanned pages.
Minchan Kim mentioned that this can also happen in the case of a THP
page where the scanned is 1 and reclaimed could be 512.

mm: remove shmem_mapping() shmem_zero_setup() duplicates
Remove the prototypes for shmem_mapping() and shmem_zero_setup() from
linux/mm.h, since they are already provided in linux/shmem_fs.h. But
shmem_fs.h must then provide the inline stub for shmem_mapping() when
CONFIG_SHMEM is not set, and a few more cfiles now need to #include it.

During OBEX Abort command, iOS may return the L2CAP_SAR_END packet before the normal end of the SAR packets: < ACL Data TX: Handle 21 [2/8] flags 0x00 dlen 11 torvalds#194 [hci0] 14.923741 Channel: 3080 len 7 ctrl 0x060a [PSM 4101 mode Enhanced Retransmission (0x03)] {chan 0} I-frame: Unsegmented TxSeq 5 ReqSeq 6 0a 06 ff 00 03 47 84 .....G. ... > ACL Data RX: Handle 21 flags 0x01 dlen 458 torvalds#382 [hci0] 19.701854 Channel: 65 len 1006 ctrl 0x460e [PSM 4101 mode Enhanced Retransmission (0x03)] {chan 0} I-frame: Start (len 32767) TxSeq 7 ReqSeq 6 0e 46 ff 7f 90 7f ff 48 7f fc 43 48 41 52 53 45 .F.....H..CHARSE ... > ACL Data RX: Handle 21 flags 0x02 dlen 552 torvalds#383 [hci0] 19.701854 > ACL Data RX: Handle 21 flags 0x01 dlen 458 torvalds#384 [hci0] 19.755918 Channel: 65 len 1006 ctrl 0xc610 [PSM 4101 mode Enhanced Retransmission (0x03)] {chan 0} I-frame: Continuation TxSeq 8 ReqSeq 6 10 c6 6e 6f 73 61 69 72 65 73 64 65 73 69 67 6e ..nosairesdesign ... > ACL Data RX: Handle 21 flags 0x02 dlen 552 torvalds#385 [hci0] 19.775016 > ACL Data RX: Handle 21 flags 0x01 dlen 458 torvalds#386 [hci0] 19.775024 Channel: 65 len 1006 ctrl 0xc612 [PSM 4101 mode Enhanced Retransmission (0x03)] {chan 0} I-frame: Continuation TxSeq 9 ReqSeq 6 12 c6 69 63 6f 20 43 69 74 79 20 54 65 63 68 20 ..ico City Tech ... > ACL Data RX: Handle 21 flags 0x02 dlen 552 torvalds#387 [hci0] 19.775024 > ACL Data RX: Handle 21 flags 0x01 dlen 458 torvalds#388 [hci0] 19.821542 Channel: 65 len 1006 ctrl 0xc614 [PSM 4101 mode Enhanced Retransmission (0x03)] {chan 0} I-frame: Continuation TxSeq 10 ReqSeq 6 14 c6 6c 74 69 6e 67 20 50 61 72 74 6e 65 72 0d ..lting Partner. ... > ACL Data RX: Handle 21 flags 0x02 dlen 552 torvalds#389 [hci0] 19.821610 > ACL Data RX: Handle 21 flags 0x01 dlen 458 torvalds#390 [hci0] 19.821610 Channel: 65 len 1006 ctrl 0xc616 [PSM 4101 mode Enhanced Retransmission (0x03)] {chan 0} I-frame: Continuation TxSeq 11 ReqSeq 6 16 c6 6c 74 69 6e 67 2e 63 6f 6d 0d 0a 55 49 44 ..lting.com..UID ... > ACL Data RX: Handle 21 flags 0x02 dlen 11 torvalds#391 [hci0] 19.821610 Channel: 65 len 7 ctrl 0x8618 [PSM 4101 mode Enhanced Retransmission (0x03)] {chan 0} I-frame: End TxSeq 12 ReqSeq 6 18 86 a0 00 03 3e 5d .....>] < ACL Data TX: Handle 21 [1/8] flags 0x00 dlen 12 torvalds#392 [hci0] 19.822491 L2CAP: Disconnection Request (0x06) ident 10 len 4 Destination CID: 3080 Source CID: 65 In this case the re-assembled packet should be 32767 bytes as defined in Start packet (torvalds#382), i.e. 33 segmented packets, but the End packet is sent as the 6th packet. The l2cap_reassemble_sdu() function returns error -EINVAL if reassembled packet size != expected size, triggering the L2CAP disconnection, which disconnects the OBEX session, preventing further OBEX actions. Log this, discard previous segmented packet data and only send data from SAR End packet to upstream. Closes: bluez/bluetooth-next#17 Signed-off-by: Frédéric Danis <frederic.danis@collabora.com>
