Hi Linus,
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.
Please pull!
