Pull block fixes from Jens Axboe:
 "Here's a pull request for 4.11-rc, fixing a set of issues mostly
  centered around the new scheduling framework. These have been brewing
  for a while, but split up into what we absolutely need in 4.11, and
  what we can defer until 4.12. These are well tested, on both single
  queue and multiqueue setups, and with and without shared tags. They
  fix several hangs that have happened in testing.

  This is obviously larger than I would have preferred at this point in
  time, but I don't think we can shave much off this and still get the
  desired results.

  In detail, this pull request contains:

   - a set of five fixes for NVMe, mostly from Christoph and one from
     Roland.

   - a series from Bart, fixing issues with dm-mq and SCSI shared tags
     and scheduling. Note that one of those patches commit messages may
     read like an optimization, but it is in fact an important fix for
     queue restarts in particular.

   - a series from Omar, most importantly fixing a hang with multiple
     hardware queues when we fail to get a driver tag. Another important
     fix in there is for resizing hardware queues, which nbd does when
     handling multiple sockets for one connection.

   - fixing an imbalance in putting the ctx for hctx request allocations
     from Minchan"
