Right, the below should take care of it. Although I think it makes sense to get this into at least 4.3 even if we won't use it until 4.4. Simply because we already export sched_setscheduler(). If you agree I guess we could route via -tip.
Thanks, Davidlohr

... just like regular sched_setscheduler(). We need this, for locktorture otherwise we can fail to build modules, ie:
ERROR: "sched_setscheduler_nocheck" [kernel/locking/locktorture.ko] undefined!
