Subject: [PATCH 0/2] sched/fair: Improve cost accounting of newidle_balance

Improve the precision of the cost of newidle_balance by taking into account
the time spent in updating blocked load and skipping load balance loop 
entirely if there is no chance to run at least one.

Vincent Guittot (2):
  sched/fair: account update_blocked_averages in newidle_balance cost
  sched/fair: Skip update_blocked_averages if we are defering load
    balance
