Merge tag 'for-linus-20180803' of git://git.kernel.dk/linux-block

Pull block fix from Jens Axboe:
 "Just a single fix, from Ming, fixing a regression in this cycle where
  the busy tag iteration was changed to only calling the callback
  function for requests that are started. We really want all non-free
  requests.

  This fixes a boot regression on certain VM setups"
