----------------------------------------------------------------
All stable@ fixes:

- Fix DM thinp btree corruption seen when inserting a new key/value pair
  into a full root node.

- Fix DM thinp btree removal deadlock due to artificially low number of
  allowed concurrent locks allowed.

- Fix possible DM crypt corruption if kernel keyring service is used.
  Only affects ciphers using following IVs: essiv, lmk and tcw.

- Two DM crypt device initialization error checking fixes.

- Fix DM integrity to allow use of async ciphers that require DMA.
