Merge tag 'for-4.19/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm

Pull device mapper updates from Mike Snitzer:

 - A couple stable fixes for the DM writecache target.

 - A stable fix for the DM cache target that fixes the potential for
   data corruption after an unclean shutdown of a cache device using
   writeback mode.

 - Update DM integrity target to allow the metadata to be stored on a
   separate device from data.

 - Fix DM kcopyd and the snapshot target to cond_resched() where
   appropriate and be more efficient with processing completed work.

 - A few fixes and improvements for DM crypt.

 - Add DM delay target feature to configure delay of flushes independent
   of writes.

 - Update DM thin-provisioning target to include metadata_low_watermark
   threshold in pool status.

 - Fix stale DM thin-provisioning Documentation.
