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.
