Thanks a lot. So far is so good for me. But I am also thinking about a feature in trace event definition. There is a parameter in TRACE_EVENT, which opts for whether this trace is taken at the start and end of the tracing (just like what I wanted). And a default trace info. Maybe others also need this.
