Merge tag 'dm-4.3-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm ...
Pull device mapper update from Mike Snitzer:
- 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
[ I did not pull the slab changes, which weren't appropriate for this
tree, and weren't obviously the right thing to do anyway. At the very
least they need some discussion and explanation before getting merged.
Because not pulling the actual tagged commit but doing a partial pull
instead, this merge commit thus also obviously is missing the git
signature from the original tag ]
