Srivatsa Vaddagiri 207d78dd26 sched: Add userspace interface to set PF_WAKE_UP_IDLE ... sched_prefer_idle flag controls whether tasks can be woken to any available idle cpu. It may be desirable to set sched_prefer_idle to 0 so that most tasks wake up to non-idle cpus under mostly_idle threshold and have specialized tasks override this behavior through other means. PF_WAKE_UP_IDLE flag per task provides exactly that. It lets tasks with PF_WAKE_UP_IDLE flag set be woken up to any available idle cpu independent of sched_prefer_idle flag setting. Currently only kernel-space API exists to set PF_WAKE_UP_IDLE flag for a task. This patch adds a user-space API (in /proc filesystem) to set PF_WAKE_UP_IDLE flag for a given task. /proc/[pid]/sched_wake_up_idle file can be written to set or clear PF_WAKE_UP_IDLE flag for a given task.
