#     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.
#
