Merge tag 'for-6.3/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm

Pull device mapper updates from Mike Snitzer:

 - Fix DM cache target to free background tracker work items, otherwise
   slab BUG will occur when kmem_cache_destroy() is called.

 - Improve 2 of DM's shrinker names to reflect their use.

 - Fix the DM flakey target to not corrupt the zero page. Fix dm-flakey
   on 32-bit hughmem systems by using bvec_kmap_local instead of
   page_address. Also, fix logic used when imposing the
   "corrupt_bio_byte" feature.

 - Stop using WQ_UNBOUND for DM verity target's verify_wq because it
   causes significant Android latencies on ARM64 (and doesn't show real
   benefit on other architectures).

 - Add negative check to catch simple case of a DM table referencing
   itself. More complex scenarios that use intermediate devices to
   self-reference still need to be avoided/handled in userspace.

 - Fix DM core's resize to only send one uevent instead of two. This
   fixes a race with udev, that if udev wins, will cause udev to miss
   uevents (which caused premature unmount attempts by systemd).

 - Add cond_resched() to workqueue functions in DM core, dn-thin and
   dm-cache so that their loops aren't the cause of unintended cpu
   scheduling fairness issues.

 - Fix all of DM's checkpatch errors and warnings (famous last words).
   Various other small cleanups.
