dm: fix handling of multiple internal suspends (2015-01-24 14:50:08 -0500)
Please pull, thanks.
Mike
----------------------------------------------------------------
2 stable fixes for dm-cache and 1 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.
