Pull block fixes from Jens Axboe:
"Was going to send this one in later this week, but given that -Werror
is now enabled (or at least available), the mq-deadline fix really
should go in for the folks hitting that.
- Ensure dd_queued() is only there if needed (Geert)
- Fix a kerneldoc warning for bio_alloc_kiocb()
- BFQ fix for queue merging
- loop locking fix (Tetsuo)"
