2008-10-09	block: use rq complete marking in blk_abort_request()	Jens Axboe	1	-0/+2
	We cannot abort a request if we raced with the timeout handler already, or with the IO completion. So make blk_abort_request() mark the request as complete, and only continue if we succeeded.

2008-10-09	block: add fault injection mechanism for faking request timeouts	Jens Axboe	1	-0/+59
	Only works for the generic request timer handling. Allows one to sporadically ignore request completions, thus exercising the timeout handling. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2008-10-09	block: unify request timeout handling	Jens Axboe	1	-0/+155
	Right now SCSI and others do their own command timeout handling. Move those bits to the block layer. Instead of having a timer per command, we try to be a bit more clever and simply have one per-queue. This avoids the overhead of having to tear down and setup a timer for each command, so it will result in a lot less timer fiddling.
