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

Pull block follow-up bits from Jens Axboe:
 "A few minor (but important) fixes for blk-mq for the -rc1 window.

   - Hot removal potential oops fix for single queue devices.  From me.

   - Two merged patches in late May meant that we accidentally lost a
     fix for freeing an active queue.  Fix that up.  From me.

   - A change of the blk_mq_tag_to_rq() API, passing in blk_mq_tags, to
     make life considerably easier for scsi-mq.  From me.

   - A schedule-while-atomic fix from Ming Lei, which would hit if the
     tag space was exhausted.

   - Missing __percpu annotation in one place in blk-mq.  Found by the
     magic Wu compile bot due to code being moved around by the previous
     patch, but it's actually an older issue.  From Ming Lei.

   - Clearing of tag of a flush request at end_io time.  From Ming Lei"
