Merge tag 'trace-v4.4-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing fix from Steven Rostedt: "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" * tag 'trace-v4.4-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Add sched_wakeup_new and sched_waking tracepoints for pid filter
