Sorry, I've been at collab summit / lsf. Plus, it's a bit too late for for-3.10 anyway. Anyways, after glancing over it, here are my preliminary thoughts. The first one looks good but I'm not sure about dropping nr_running adjustment. The only real benefit coming from that is dropping a sched callback and if there's any performance / overhead impact, I'm afraid it's gonna be negative. There are actual benefits in using as few tasks as possible - the cache footprint gets smaller, so unless there's a clear indication that the suggested behavior is better in some way, I'm not sure what we're buying with the proposed changes.
