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

Pull blkcg fix from Jens Axboe:
 "One final fix that should go into 4.3.  It's a simple 2x1 liner,
  fixing a blkcg accounting issue.  It was using the wrong bio member to
  look at the sync and write bits..."

* 'for-linus' of git://git.kernel.dk/linux-block:
  blkcg: fix incorrect read/write sync/async stat accounting
