Linus Torvalds b80fed9595 - 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

   interface

 - make DM multipath's fast code-paths lockless, using lockless_deference,

   The m->lock spinlock contention was a serious bottleneck.
