  docs: dm-integrity: remove reference to ARC4 (2019-12-10 10:02:43 -0500)

Please pull, thanks!

----------------------------------------------------------------
- Fix DM multipath by restoring full path selector functionality for
  bio-based configurations that don't haave a SCSI device handler.

- Fix dm-btree removal to ensure non-root btree nodes have at least
  (max_entries / 3) entries.  This resolves userspace thin_check
  utility's report of "too few entries in btree_node".

- Fix both the DM thin-provisioning and dm-clone targets to properly
  flush the data device prior to metadata commit.  This resolves the
  potential for inconsistency across a power loss event when the data
  device has a volatile writeback cache.

- Small documentation fixes to dm-clone and dm-integrity.
