Hi,

The 1st patch fixes one race between timeout and dying queue.

The 2nd patch add comments on races with timeout handler.

The 3rd patch improves handling for dying queue.


V1:
	- add comments on races related with timeout handler
	- add Tested-by & Reviewed-by tag

thanks,
Ming

  blk-mq: don't complete un-started request in timeout handler
  blk-mq: comment on races related timeout handler
  blk-mq: start to freeze queue just after setting dying
