From: Ming Lei
Date: Thu Dec 26 2013 - 08:31:53 EST
Hi,
The 1st one moves request initializtion out of completion handler.
The following 2 patches support drain/sync mq queue in blk_cleanup_queue.
The 4th patch calls blk_cleanup_queue() in removing device path
to fix queue leak problem.
The 5th patch doesn't export blk_mq_free_queue() because the function
is called in release handler of queue kobject, and drivers needn't
to call it.
V1:
- add patch 1/5
- add comments on blk_execute_rq_nowait 2/5
- set QUEUE_FLAG_DEAD for MQ 2/5
- use __blk_mq_drain_queue() helper 2/5
