[PATCH v3 09/10] sched/fair: use load instead of runnable load in wakeup path

2019-09-19 Thread Vincent Guittot
runnable load has been introduced to take into account the case where blocked load biases the wake up path which may end to select an overloaded CPU with a large number of runnable tasks instead of an underutilized CPU with a huge blocked load. Tha wake up path now starts to looks for idle CPUs
