I like this, I've had run-this-queue wired up as well from sysfs in the past. Maybe we should push it one further, and also allow things like running a stopped queue? Would probably be nicer if the file accepted input like "run" (which would be your current run-this-queue) and "start" (start stopped queues). Then we could also EINVAL writes that we don't grok, instead of just blindly always running the queue. -- Jens Axboe
