Merge tag 'dm-4.2-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper fixes from Mike Snitzer:
- revert a request-based DM core change that caused IO latency to
increase and adversely impact both throughput and system load
- fix for a use after free bug in DM core's device cleanup
- a couple DM btree removal fixes (used by dm-thinp)
- a DM thinp fix for order-5 allocation failure
- a DM thinp fix to not degrade to read-only metadata mode when in
out-of-data-space mode for longer than the 'no_space_timeout'
- fix a long-standing oversight in both dm-thinp and dm-cache by now
exporting 'needs_check' in status if it was set in metadata
- fix an embarrassing dm-cache busy-loop that caused worker threads to
eat cpu even if no IO was actively being issued to the cache device
* tag 'dm-4.2-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm:
dm cache: avoid calls to prealloc_free_structs() if possible
dm cache: avoid preallocation if no work in writeback_some_dirty_blocks()
dm cache: do not wake_worker() in free_migration()
dm cache: display 'needs_check' in status if it is set
dm thin: display 'needs_check' in status if it is set
dm thin: stay in out-of-data-space mode once no_space_timeout expires
dm: fix use after free crash due to incorrect cleanup sequence
Revert "dm: only run the queue on completion if congested or no requests pending"
dm btree: silence lockdep lock inversion in dm_btree_del()
dm thin: allocate the cell_sort_array dynamically
dm btree remove: fix bug in redistribute3
