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
