Revision 776e49e8ddb5169e6477fd33a396e9c7b2eb7400 authored by Linus Torvalds on 04 March 2020, 19:02:45 UTC, committed by Linus Torvalds on 04 March 2020, 19:02:45 UTC 
Merge tag 'for-5.6/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
 
Pull device mapper fixes from Mike Snitzer:

 - Fix request-based DM's congestion_fn and actually wire it up to the
   bdi.

 - Extend dm-bio-record to track additional struct bio members needed by
   DM integrity target.

 - Fix DM core to properly advertise that a device is suspended during
   unload (between the presuspend and postsuspend hooks). This change is
   a prereq for related DM integrity and DM writecache fixes. It
   elevates DM integrity's 'suspending' state tracking to DM core.

 - Four stable fixes for DM integrity target.

 - Fix crash in DM cache target due to incorrect work item cancelling.

 - Fix DM thin metadata lockdep warning that was introduced during 5.6
   merge window.

 - Fix DM zoned target's chunk work refcounting that regressed during
   recent conversion to refcount_t.

 - Bump the minor version for DM core and all target versions that have
   seen interface changes or important fixes during the 5.6 cycle.
