During the merge window I added a new file that is used to filter trace

events on pids. It filters all events where only tasks with their pid in that
 file exists. It also handles the sched_switch and sched_wakeup trace events
 where the current task does not have its pid in the file, but the task
 either being switched to or awaken does.
 
 Unfortunately, I forgot about sched_wakeup_new and sched_waking. Both of
 these tracepoints use the same class as the sched_wakeup tracepoint, and
 they too should be included in what gets filtered by the set_event_pid file.
