- Fix double free when the reg() call fails in event_trigger_callback()
- Fix anomoly of snapshot causing tracing_on flag to change
- Add selftest to test snapshot and tracing_on affecting each other
- Fix setting of tracepoint flag on error that prevents probes from
being deleted.
- Fix another possible double free that is similar to event_trigger_callback()
- Quiet a gcc warning of a false positive unused variable
- Fix crash of partial exposed task->comm to trace events
