    sched: Disable energy-unfriendly nohz kicks · f05d25b9
    Morten Rasmussen authored
    With energy-aware scheduling enabled nohz_kick_needed() generates many
    nohz idle-balance kicks which lead to nothing when multiple tasks get
    packed on a single cpu to save energy. This causes unnecessary wake-ups
    and hence wastes energy. Make these conditions depend on !energy_aware()
    for now until the energy-aware nohz story gets sorted out.
