Hello.
This is an extension of the simplification patch posted previously. The original goal was to make the code a bit more readable but I noticed a bug meanwhile and included it in the series.
Reason for RFC: - I noticed an asymmetry in update_cfs_group(se) calls between unthrottle_cfs_rq() and enqueue_task_fair(), not sure if the omission is warranted. It's marked XXX in the patch "sched/fair: Simplify ancestor enqueue loops"
Patch 1 - fix of load_cfs_rq_list handling
Patches 2, 3 - just (re)naming things
Patch 4, 5 - simplifications of load_cfs_rq_list and ancestor processing loops - no functional changes intended
RFC v1: https://lore.kernel.org/r/20210225162757.48858-1-mkoutny@suse.com
Michal Koutný (5): sched/fair: Add ancestors of unthrottled undecayed cfs_rq sched: Add group_se() helper sched/fair: Rename leaf_list to more fitting load_list sched/fair: Simplify load_cfs_rq_list maintenance sched/fair: Simplify ancestor enqueue loops
