[RFC PATCH 0/3] Aggregate task utilization only on root cfs_rq

[Dietmar Eggemann]

This is an alternative approach to '[RFC PATCH v2] sched: reflect
sched_entity movement into task_group's utilization' which requires
'[RFC PATCH] sched: fix hierarchical order in rq->leaf_cfs_rq_list'

The patch-set doesn't currently handle the impact of cfs throttling on
utilization.

[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.

Dietmar Eggemann (3):
  sched/fair: Aggregate task utilization only on root cfs_rq
  sched/fair: Sync se with root cfs_rq
  sched/fair: Change @running of __update_load_avg() to @update_util
