- 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.

Pointer variables of void * type do not require type cast.
