to dependency on the new blk_mq_delay_kick_requeue_list().

blk-mq: introduce blk_mq_delay_kick_requeue_list() (2016-09-14 11:48:34 -0600)

dm mpath: always return reservation conflict without failing over (2016-09-29 10:57:07 -0400)
Please pull, thanks.
Mike
----------------------------------------------------------------
. various fixes and cleanups for request-based DM core
. add support for delaying the requeue of requests; used by DM multipath
when all paths have failed and 'queue_if_no_path' is enabled
. DM cache improvements to speedup the loading metadata and the writing
of the hint array
. fix potential for a dm-crypt crash on device teardown
. remove dm_bufio_cond_resched() and just using cond_resched()
. change DM multipath to return a reservation conflict error
immediately; rather than failing the path and retrying (potentially
indefinitely)
