Thanks, I may look at these in the future to update my tests. I've
attached some trigger tests that I just wrote up.

ftrace-event-traceon-off : tests the traceon and traceoff triggers.
  - enables tracing, sets traceoff trigger, checks if it disables
  - disables tracing, sets traceon trigger, checks if it enables
  - does a countdown from 3 to make sure the tracing is disabled
     3 times.

ftrace-event-stacktrace  : tests the event stack trace. It
  - checks enabling of events (non trigger)
  - checks enabling only the stack trace
  - checks enabling both the stack trace and events
  - checks if the count works from 1 2 or 3 times

ftrace-event-trigger-event : tests enable/disable_event trigger
  - checks if the event enables another event (several times)
  - checks if the event disables another event (several times)
  - checks if it enables an event count times "1 2 3"
  - then it tests the filter part of the event trigger (enable only)

Feel free to add onto these.
