Some of this feels quite heavy-handed, and I imagine that having to take the lock in every request could cause considerable lock contention only so that we can iterate all requests in a slow path. This works for now, but maybe in the long run, we want to teach the SCSI layer about (virt)queues, and have a separate request list per queue (= AioContext)? Kevin
