[BLOCK] as-iosched: update alias handling
Unlike other ioscheds, as-iosched handles alias by chaing them using rq->queuelist. As aliased requests are very rare in the first place, this complicates merge/dispatch handling without meaningful performance improvement. This patch updates as-iosched to dump aliased requests into dispatch queue as other ioscheds do. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jens Axboe <axboe@suse.de>
