  dm integrity: fix deadlock with overlapping I/O (2019-04-05 18:49:08 -0400)

Please pull, thanks.
Mike

----------------------------------------------------------------
- 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.
