Merge tag 'dm-3.19-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper fixes from Mike Snitzer:
"Two stable fixes for dm-cache and one 3.19 DM core fix:
- fix potential for dm-cache metadata corruption via stale metadata
buffers being used when switching an inactive cache table to
active; this could occur due to each table having it's own bufio
client rather than sharing the client between tables.
- fix dm-cache target to properly account for discard IO while
suspending otherwise IO quiescing could complete prematurely.
- fix DM core's handling of multiple internal suspends by maintaining
an 'internal_suspend_count' and only resuming the device when this
count drops to zero"

dm: fix handling of multiple internal suspends
