| +The events which are available for tracing can be found in the file
| +/sys/kernel/debug/tracing/available_events.
| +
| +To enable a particular event, such as 'sched_wakeup', simply echo it to
| +/sys/debug/tracing/set_event. For example:
| +
| + # echo sched_wakeup > /sys/kernel/debug/tracing/set_event
| +
| +To disable an event, echo the event name to the set_event file prefixed
| +with an exclamation point:
| +
| + # echo '!sched_wakeup' >> /sys/kernel//debug/tracing/set_event
^^^
Since it's just being added and easy to fix (later maybe via trivial tree),
I suppose here is quite a small misprint :)
| +
| +To disable events, echo an empty line to the set_event file:
| +
| + # echo > /sys/kernel/debug/tracing/set_event
