    Linus Torvalds authored
    Pull core block updates from Jens Axboe:
     "We don't have a lot of core changes this time around, it's mostly in
      drivers, which will come in a subsequent pull.
      The cores changes include:
       - blk-mq
            - Prep patch from Christoph, changing blk_mq_alloc_request() to
              take flags instead of just using gfp_t for sleep/nosleep.
            - Doc patch from me, clarifying the difference between legacy
              and blk-mq for timer usage.
            - Fixes from Raghavendra for memory-less numa nodes, and a reuse
              of CPU masks.
       - Cleanup from Geliang Tang, using offset_in_page() instead of open
         coding it.
       - From Ilya, rename request_queue slab to it reflects what it holds,
         and a fix for proper use of bdgrab/put.
       - A real fix for the split across stripe boundaries from Keith.  We
         yanked a broken version of this from 4.4-rc final, this one works.
       - From Mike Krinkin, emit a trace message when we split.
       - From Wei Tang, two small cleanups, not explicitly clearing memory
         that is already cleared"

      blk-mq: add a flags parameter to blk_mq_alloc_request
      Revert "blk-flush: Queue through IO scheduler when flush not required"
      block: clarify blk_add_timer() use case for blk-mq
