  dm writecache: fix a crash due to reading past end of dirty_bitmap (2018-08-16 13:43:01 -0400)

Please pull, thanks!
Mike

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