    Subject[PATCH 0/3] sched/fair: Reduce contention on tg's load_avg
    Date
    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
