Merge tag 'for-5.1/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper fixes from Mike Snitzer:
- Two queue_limits stacking fixes: disable discards if underlying
driver does. And propagate BDI_CAP_STABLE_WRITES to fix sporadic
checksum errors.
- Fix that reverts a DM core limit that wasn't needed given that
dm-crypt was already updated to impose an equivalent limit.
- Fix dm-init to properly establish 'const' for __initconst array.
- Fix deadlock in DM integrity target that occurs when overlapping IO
is being issued to it. And two smaller fixes to the DM integrity
target.

dm integrity: fix deadlock with overlapping I/O
dm: disable DISCARD if the underlying storage no longer supports it
dm table: propagate BDI_CAP_STABLE_WRITES to fix sporadic checksum errors
dm: revert 8f50e358153d ("dm: limit the max bio size as BIO_MAX_PAGES * PAGE_SIZE")
dm init: fix const confusion for dm_allowed_targets array
dm integrity: make dm_integrity_init and dm_integrity_exit static
dm integrity: change memcmp to strncmp in dm_integrity_ctr
