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.
