Hi Linus,

Merging these DM changes will require manual conflict resolution in the
snapshot target's Documentation updates due to conflicts with the
shotgun blast of RST changes to DM documentation that I didn't ack but
got in anyway -- clearly the RST Documentation train brakes for nobody ;)
Feel free to have a look at the test merge I did in the linux-dm.git
'dm-5.3-merge' branch.

Also, you'll note that the last 2 commits of this pull were rebased
today; I did that because the dm-bufio fix's commit header needed a lot
of grammar fixes and was also missing the stable@vger.kernel.org Cc.

The following changes since commit 2eba4e640b2c4161e31ae20090a53ee02a518657:

  dm verity: use message limit for data block corruption message (2019-06-25 14:09:14 -0400)

  dm bufio: fix deadlock with loop device (2019-07-12 09:59:37 -0400)

Please pull, thanks!
Mike

----------------------------------------------------------------
- Add encrypted byte-offset initialization vector (eboiv) to DM crypt.

- Add optional discard features to DM snapshot which allow freeing space
  from a DM device whose free space was exhausted.

- Various small improvements to use struct_size() and kzalloc().

- Fix to check if DM thin metadata is in fail_io mode before attempting
  to update the superblock to set the needs_check flag.  Otherwise the
  DM thin-pool can hang.

- Fix DM bufio shrinker's potential for ABBA recursion deadlock with DM
  thin provisioning on loop usecase.
