Subject[PATCH 0/2] tracing: Add a way to have custom events in the tracefs directory
We would like to have in production a way to record sched wakeups and
sched switch, and be able to save the information in a small file
with as much available as possible. Currently the wake up and sched switch
events are 36 and 64 bytes each (plus a 4 byte ring buffer event header).

By having a custom module tap into the sched switch and waking trace points
we can bring those events down to 16 and 14 bytes respectively.

Steven Rostedt (Google) (2):
tracing: Allow custom events to be added to the tracefs directory
tracing: Add sample code for custom trace events
