Subject: Can mei_timer() turn itself off when not needed?
On my laptop, the kernel has become good enough at idling that
mei_timer() accounts for a decent fraction of wakeups. It looks like,
unless something interesting is going on, it mostly just iterates over
some empty lists and re-queues itself. Could it learn to stop
re-queueing itself if there isn't anything for it to do?
