Hi Linus,
The following changes since commit 34dd051741572859bc1fef525c5ddbc127158b52:
dm cache policy smq: move 'dm-cache-default' module alias to SMQ (2015-08-12 11:27:29 -0400)

dm: disable slab merging for all DM slabs (2015-09-02 08:53:47 -0400)
Please pull, thanks.
Mike
----------------------------------------------------------------
- a couple small cleanups in dm-cache, dm-verity, persistent-data's
dm-btree, and DM core.
- a 4.1-stable fix for dm-cache that fixes the leaking of deferred bio
prison cells
- a 4.2-stable fix that adds feature reporting for the dm-stats features
added in 4.2
- improve DM-snapshot to not invalidate the on-disk snapshot if snapshot
device write overflow occurs; but a write overflow triggered through
the origin device will still invalidate the snapshot.
- optimize DM-thinp's async discard submission a bit now that late bio
splitting has been included in block core.
- switch DM-cache's SMQ policy lock from using a mutex to a spinlock;
improves performance on very low latency devices (eg. NVMe SSD).
- document DM RAID 4/5/6's discard support
- last but not least: add SLAB_NO_MERGE flag to mm/slab_common and
disable slab merging for all of DM's slabs (XFS will also use
SLAB_NO_MERGE once merged).
