    Pull block layer updates from Jens Axboe:
     "This is the first pull request for 4.14, containing most of the code
      changes. It's a quiet series this round, which I think we needed after
      the churn of the last few series. This contains:
       - Fix for a registration race in loop, from Anton Volkov.
       - Overflow complaint fix from Arnd for DAC960.
       - Series of drbd changes from the usual suspects.
       - Conversion of the stec/skd driver to blk-mq. From Bart.
       - A few BFQ improvements/fixes from Paolo.
       - CFQ improvement from Ritesh, allowing idling for group idle.
       - A few fixes found by Dan's smatch, courtesy of Dan.
       - A warning fixup for a race between changing the IO scheduler and
         device remova. From David Jeffery.
       - A few nbd fixes from Josef.
       - Support for cgroup info in blktrace, from Shaohua.
       - Also from Shaohua, new features in the null_blk driver to allow it
         to actually hold data, among other things.
       - Various corner cases and error handling fixes from Weiping Zhang.
       - Improvements to the IO stats tracking for blk-mq from me. Can
         drastically improve performance for fast devices and/or big
       - Series from Christoph removing bi_bdev as being needed for IO
         submission, in preparation for nvme multipathing code.
       - Series from Bart, including various cleanups and fixes for switch
         fall through case complaints"
