[PATCH 0/3] Reduce number of active LB

From: Vincent Guittot

Few improvements related to active LB and the increase of LB interval.
I haven't seen any performcne impact on various benchmarks except for
-stress-ng mmapfork : +4.54% on my octo-core arm64
But this was somewhat expected as the changes impact mainly corner cases.

Vincent Guittot (3):
sched/fair: skip idle cfs_rq
sched/fair: don't set LBF_ALL_PINNED unnecessarily
sched/fair: reduce cases for active balance
