[PATCH] noop-iosched: avoid corrupted request merging
Tejun Heo notes: "I'm currently debugging this. The problem is that we are using the generic dispatch queue directly in the noop sched and merging is NOT allowed on dispatch queues but generic handling of last_merge tries to merge requests. I'm still trying to verify this, so I'll be back with results soon." In the meantime, disable merging for noop by setting REQ_NOMERGE in elevator_noop_add_request(). Eventually, we should add a noop_list and do the dispatching like in the other io schedulers. Merging is still beneficial for noop (and it has always done it).
