dm cache: handle kmalloc failure allocating background_tracker struct (2017-05-17 09:44:53 -0400)
Please pull, thanks.

----------------------------------------------------------------
- A couple DM thin provisioning fixes
- A few request-based DM and DM multipath fixes for issues that were
made when merging Christoph's changes with Bart's changes for 4.12
- A DM bufio unsigned overflow fix
- A couple pure fixes for the DM cache target.
- Various very small tweaks to the DM cache target that enable
considerable speed improvements in the face of continuous IO. Given
that the cache target was significantly reworked for 4.12 I see no
reason to sit on these advances until 4.13 considering the favorable
results associated with such minimalist tweaks.
----------------------------------------------------------------
Christoph Hellwig (3):
dm rq: add a missing break to map_request
dm mpath: don't return -EIO from dm_report_EIO
dm mpath: multipath_clone_and_map must not return -EIO
Colin Ian King (1):
dm cache: handle kmalloc failure allocating background_tracker struct
Joe Thornber (10):
dm cache: fix incorrect 'idle_time' reset in IO tracker
dm cache policy smq: only demote entries in bottom half of the clean multiqueue
dm cache policy smq: be more aggressive about triggering a writeback
dm cache policy smq: put newly promoted entries at the top of the multiqueue
dm cache policy smq: stop preemptively demoting blocks
dm cache: track all IO to the cache rather than just the origin device's IO
dm cache: simplify the IDLE vs BUSY state calculation
dm cache policy smq: don't do any writebacks unless IDLE
dm thin metadata: call precommit before saving the roots
dm space map disk: fix some book keeping in the disk space map
Mikulas Patocka (1):
dm bufio: make the parameter "retain_bytes" unsigned long
