[PATCHSET 0/3] Split queue lock into submission/completion locks

[Jens Axboe]

This series is on top of the previous work from yesterday, including
Christophs patch. It splits nvmeq->q_lock into two locks:

1) ->sq_lock, that protects the submission side of things
2) ->cq_lock, that protects the completion side

This also means that we can drop the IRQ safe nature of the submission
side locking.
