Summary

In the Linux kernel, the following vulnerability has been resolved: sched/fair: Fix NEXT_BUDDY Adam reports that enabling NEXT_BUDDY insta triggers a WARN in pick_next_entity(). Moving clear_buddies() up before the delayed dequeue bits ensures no ->next buddy becomes delayed. Further ensure no new ->next buddy ever starts as delayed.
