I misunderstood you. This is a appropriate file to place the matching function.
I have moved it to this file.

I checked the regex_match_foo  functions in  trace_events_filter.c. Per my
reading, I think it's a little tedious, and only support '*' character. They are
glued with tracing framework. So i gave up to re-used them.

I will send new version patch set to you later.

Thanks!
