[PATCH] sched/fair: Fix negative energy delta in find_energy_efficient_cpu()

2021-04-20 Thread Pierre . Gondois
From: Pierre Gondois find_energy_efficient_cpu() (feec()) searches the best energy CPU to place a task on. To do so, compute_energy() estimates the energy impact of placing the task on a CPU, based on CPU and task utilization signals. Utilization signals can be concurrently updated while
