  dm snapshot: add new persistent store option to support overflow (2015-10-09 16:57:03 -0400)

Please pull, thanks.

----------------------------------------------------------------
3 stable@ fixes:

- DM core AB-BA deadlock fix in the device destruction path (vs device
  creation's DM table swap).

- DM raid fix to properly round up the region_size to the next
  power-of-2.

- DM cache fix for a NULL pointer seen while switching from the
  "cleaner" cache policy.

2 fixes for regressions introduced during the 4.3 merge:

- request-based DM error propagation regressed due to incorrect
  changes introduced when adding the bi_error field to bio.

- DM snapshot fix to only support snapshots that overflow if the client
  (e.g. lvm2) is prepared to deal with the associated snapshot status
  interface change.
