This patch series tries to reduce contention on task_group's load_avg
to improve system performance. It also tries to optimize the use of
idle_cpu() call in update_sg_lb_stats().
Waiman Long (3):
sched/fair: Avoid redundant idle_cpu() call in update_sg_lb_stats()
sched/fair: Move hot load_avg into its own cacheline
sched/fair: Use different cachelines for readers and writers of
load_avg
