Reads on a known bad disk can read corrupt cache metadata, which causes a crash. Abort reads early on a bad disk so that ATS is less likely to crash after a disk is marked bad.

Perhaps this should go before trying the lock. Do you really want to reschedule for the lock if the disk is bad? |

There was a problem hiding this comment.
The new code should really be outside the brace at line 2182, because that's for scoping the mutex. You can commit this or I'll approve an update with that change.
