Merge tag 'dm-4.9-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper updates from Mike Snitzer: - 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) * tag 'dm-4.9-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: (24 commits) dm mpath: always return reservation conflict without failing over dm bufio: remove dm_bufio_cond_resched() dm crypt: fix crash on exit dm cache metadata: switch to using the new cursor api for loading metadata dm array: introduce cursor api dm btree: introduce cursor api dm cache policy smq: distribute entries to random levels when switching to smq dm cache: speed up writing of the hint array dm array: add dm_array_new() dm mpath: delay the requeue of blk-mq requests while all paths down dm mpath: use dm_mq_kick_requeue_list() dm rq: introduce dm_mq_kick_requeue_list() dm rq: reduce arguments passed to map_request() and dm_requeue_original_request() dm rq: add DM_MAPIO_DELAY_REQUEUE to delay requeue of blk-mq requests dm: convert wait loops to use autoremove_wake_function() dm: use signal_pending_state() in dm_wait_for_completion() dm: rename task state function arguments dm: add two lockdep_assert_held() statements dm rq: simplify dm_old_stop_queue() dm mpath: check if path's request_queue is dying in activate_path() ...
