dm array: fix a reference counting bug in shadow_ablock (2013-12-13 14:22:10 -0500)
Please pull, thanks.

----------------------------------------------------------------
A set of device-mapper fixes for 3.13.
A fix for possible memory corruption during DM table load, fix a
possible leak of snapshot space in case of a crash, fix a possible
deadlock due to a shared workqueue in the delay target, fix to
initialize read-only module parameters that are used to export metrics
for dm stats and dm bufio.
Quite a few stable fixes were identified for both the thin-provisioning
and caching targets as a result of increased regression testing using
the device-mapper-test-suite (dmts). The most notable of these are the
reference counting fixes for the space map btree that is used by the
dm-array interface -- without these the dm-cache metadata will leak,
resulting in dm-cache devices running out of metadata blocks. Also,
some important fixes related to the thin-provisioning target's
transition to read-only mode on error.
----------------------------------------------------------------
Joe Thornber (7):
dm thin: switch to read only mode if a mapping insert fails
dm thin: always fallback the pool mode if commit fails
dm thin: re-establish read-only state when switching to fail mode
dm thin: allow pool in read-only mode to transition to read-write mode
dm cache policy mq: fix promotions to occur as expected
dm space map: disallow decrementing a reference count below zero
dm array: fix a reference counting bug in shadow_ablock
Mike Snitzer (3):
dm space map metadata: return on failure in sm_metadata_new_block
dm thin: switch to read-only mode if metadata space is exhausted
dm cache: update Documentation for invalidate_cblocks's range syntax
Mikulas Patocka (5):
dm delay: fix a possible deadlock due to shared workqueue
dm snapshot: avoid snapshot space leak on crash
dm table: fail dm_table_create on dm_round_up overflow
dm bufio: initialize read-only module parameters
dm stats: initialize read-only module parameter
Vincent Pelletier (1):
dm cache: actually resize cache
