[patch 1] sched/fair: Aggregate task utilization only on root cfs_rq Prevent the utilization signal maintenance for se/cfs_rq representing task groups other than root task group. [patch 2] sched/fair: Sync se with root cfs_rq Make sure that the se (of a task) is in sync with the root cfs_rq [patch 3] sched/fair: Change @running of __update_load_avg() to @update_util Pass the information whether utilization (besides load) has to be maintained for the container element of @sa.
