This patch (as1159b) changes the timeout routines in the block core to
use round_jiffies_up(). There's no point in rounding the timer
deadline down, since if it expires too early we will have to restart
it.The patch also removes some unnecessary tests when a request is
removed from the queue's timer list.Signed-off-by: Alan Stern

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.Found and suggested by Mike Anderson

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

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.Signed-off-by: Mike Anderson
