Subject: [PATCH 0/2] avoid spurious blocked load update

This patchset is a follow up of : 
https://lore.kernel.org/lkml/20211019123537.17146-1-vincent.guittot@linaro.org/

It ensures that newly idle load balance will not kick the update of
blocked load if it skips the load balance because avg_idle is too short.
It also makes sure that rq->next_balance doesn't go in the past when
updated.

Tim Chen (1):
  sched: sched: Fix rq->next_balance time updated to earlier than
    current time

Vincent Guittot (1):
  sched/fair: skip newidle update stats
