----------------------------------------------------------------
A set of device-mapper fixes for 3.9.
Fix reported data loss with discards and thin snapshots; avoid a
deadlock observed in dm verity; fix a race in the new dm cache code
along with some other minor bugs; store the cache policy version on disk
to make the stored hints format future-proof.
----------------------------------------------------------------

dm cache: detect cache_create failure
dm cache: avoid calling policy destructor twice on error
Joe Thornber (5):
dm thin: fix discard corruption
dm thin: fix non power of two discard granularity calc
dm cache: avoid 64 bit division on 32 bit
dm cache: metadata clear dirty bits on clean shutdown

Mike Snitzer (2):
dm cache: policy change version from string to integer set
dm cache: policy ignore hints if generated by different version
