#     Merge tag 'for-5.7/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
#     
#     Pull device mapper updates from Mike Snitzer:
#     
#      - 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.
#
