Hi Matthew and Keith,

Thanks for the quick review.

The patch has been updated with the feedback from Keith and Jens. It's against
Jens' 3.16/core tree. You may use the nvmemq_wip_review branch at:

https://github.com/MatiasBjorling/linux-collab nvmemq_wip_review

Changes since v3:
* Added abortion logic
* Fixed possible race on abortion
* Removed req data with flush. Handled by by blk-mq
* Added safety check for submitting user rq to admin queue.
* Use dev->online_queues for nr_hw_queues
* Fix loop with initialization in nvme_create_io_queues
* Style fixups

Changes since v2:
* rebased on top of current 3.16/core.
* use blk-mq queue management for spreading io queues
* removed rcu handling and allocated all io queues up front for mgmt by blk-mq
* removed the need for hotplugging notification
* fixed flush data handling
* fixed double free of spinlock
* various cleanup

Keith, what kind of retry scheme do you like for timeout retries?
