[PATCH v2 0/4] block: misc changes

[Ming Lei <tom.leiming@gmail.com>]

Hi,

The 1st  patch add comments on blk-mq races with timeout handler.

The other 3 patches improves handling for dying queue:
	- the 2nd one adds one barrier in blk_queue_enter() for
	avoiding hanging caused by out-of-order
	- the 3rd and 4th patches block new I/O entering queue
	after queue is set as dying

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

thanks,
Ming
