  dm: remove unnecessary (void*) conversion in event_callback() (2023-02-20 11:52:49 -0500)

Please pull, thanks.
Mike

----------------------------------------------------------------
- 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.
