Merge tag 'dm-4.7-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper updates from Mike Snitzer:
- based on Jens' 'for-4.7/core' to have DM thinp's discard support use
bio_inc_remaining() and the block core's new async __blkdev_issue_discard()
interface
- make DM multipath's fast code-paths lockless, using lockless_deference,
to significantly improve large NUMA performance when using blk-mq.
The m->lock spinlock contention was a serious bottleneck.
- a few other small code cleanups and Documentation fixes
* tag 'dm-4.7-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm:
dm thin: unroll issue_discard() to create longer discard bio chains
dm thin: use __blkdev_issue_discard for async discard support
dm thin: remove __bio_inc_remaining() and switch to using bio_inc_remaining()
dm raid: make sure no feature flags are set in metadata
dm ioctl: drop use of __GFP_REPEAT in copy_params()'s __vmalloc() call
dm stats: fix spelling mistake in Documentation
dm cache: update cache-policies.txt now that mq is an alias for smq
dm mpath: eliminate use of spinlock in IO fast-paths
dm mpath: move trigger_event member to the end of 'struct multipath'
dm mpath: use atomic_t for counting members of 'struct multipath'
dm mpath: switch to using bitops for state flags
dm thin: Remove return statement from void function
dm: remove unused mapped_device argument from free_tio()
