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.
