fix queue_lock usage in blk-mq and nvme

2015-05-07 Thread Christoph Hellwig
Historically we always take queue_lock with irqs disabled. Blk-mq doesn't really use the queue_lock much, but when it does it needs to follow this rules to make lockdep happy. The first patch removes a queue_lock usage instead of fixing things properly, and the second is a bad-aid for nvme. In
