Subject: [git pull] device mapper fixes for 3.18
Hi Linus,
The following changes since commit 56ec16cb1e1ce46354de8511eef962a417c32c92:

dm btree: fix a recursion depth bug in btree walking code (2014-11-10 15:23:58 -0500)
Please pull, thanks.
Mike
----------------------------------------------------------------
. stable fix for dm-thin that avoids normal IO racing with discard
. stable fix for a dm-cache related bug in dm-btree walking code that
results from using very large fast device (e.g. 4T) with a very small
cache blocksize (e.g. 32K) -- this is a very uncommon configuration
. a couple fixes for dm-raid (one for stable and the other addresses a
crash in 3.18-rc1 code)
. stable fix for dm-thinp that addresses a very rare dm-bufio bug having
to do with memory reclaimation (via shrinker) when using dm-thinp
ontop of loopback devices
. fix a leak in dm-stripe target constructor's error path
----------------------------------------------------------------

dm raid: ensure superblock's size matches device's logical block size
dm raid: fix inaccessible superblocks causing oops in configure_discard_support
