Hi, Andi Kleen previously pointed out a get/set race in the sched_feat() infrastructure. I had previously proposed to address this with a new static_key set_true/set_false API:
http://www.gossamer-threads.com/lists/linux/kernel/1955879 However, I think its simpler to just add higher level locking as Ingo previously suggested, and that is how other consumers of the this interface are already operating. It seems a bit like overkill to add this new API, just for this one case. So, this locking change is in patch 2. Patch 1 is a small cleanup, but no functional change.
