[PATCH] blk: fix merge bug in as-iosched
as-iosched deals with aliased requests differently from other ioscheds. It links together aliased requests using rq->queuelist instead of spilling alises to dispatch queue like other ioscheds do. Requests linked in this way cannot be merged. Unfortunately, generic q->last_merge handling patch didn't take this into account and q->last_merge could be set to an aliased request resulting in Badness, corrupt list and eventually panic. This explicitly marks aliased requests to be unmergeable. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
