From: "Steven Rostedt (Google)" <rostedt@xxxxxxxxxxx>
After having tests constantly fail because of some left over tracing that
was still enabled before the test started, call tracefs_instance_reset()
before and after the unit tests to make sure it starts with a clean slate
and does not fail due to residual tracing that was from an external event.
