Merge tag 'for-linus-20190628' of git://

Pull block fixes from Jens Axboe:
 "Just two small fixes.

  One from Paolo, fixing a silly mistake in BFQ. The other one is from
  me, ensuring that we have ->file cleared in the io_uring request a bit
  earlier. That avoids a use-before-free, if we encounter an error
  before ->file is assigned"
