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
