  dm clone metadata: Fix return type of dm_clone_nr_of_hydrated_regions() (2020-03-27 14:42:51 -0400)

Please pull, thanks!
Mike

----------------------------------------------------------------
- Add DM writecache "cleaner" policy feature that allows cache to be
  flushed while userspace monitors for completion to then discommision
  use of caching.

- Optimize DM writecache superblock writing and also yield CPU while
  initializing writecache on large PMEM devices to avoid CPU stalls.

- Various fixes to DM integrity target while preparing for the
  ability to resize a DM integrity device.  In addition to resize
  support, add optional discard support with the "allow_discards"
  feature.

- Fix DM clone target's discard handling and overflow bugs which could
  cause data corruption.

- Fix memory leak in destructor for DM verity FEC support.

- Fix DM zoned target's redundant increment of nr_rnd_zones.

- Small cleanup in DM crypt to use crypt_integrity_aead() helper.
