- A fix for NVMe, fixing a patch that went in in the merge window. From
Keith.

- Two fixes for blk-mq CPU hotplug handling, from Ming Lei.

- bdi vs blockdev lifetime fix from Neil Brown, fixing and oops in md.

- Two blk-mq fixes from Shaohua, fixing a race on queue stop and a bad
merge issue with FUA writes.
