dm btree: fix a recursion depth bug in btree walking code (2014-11-10 15:23:58 -0500)

Please pull, thanks.

. 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

Heinz Mauelshagen (2):
dm raid: ensure superblock's size matches device's logical block size
dm raid: fix inaccessible superblocks causing oops in configure_discard_support

Joe Thornber (2):
dm thin: grab a virtual cell before looking up the mapping
dm btree: fix a recursion depth bug in btree walking code

Mikulas Patocka (1):
dm bufio: change __GFP_IO to __GFP_FS in shrinker callbacks

Pavitra Kumar (1):
dm stripe: fix potential for leak in stripe_ctr error path
