A new API is proposed, to get tep event descriptor for given synthetic
event:

tracefs_synth_get_event ()

The API implementation gets derived from the implementation of the
existing API  tracefs_dynevent_get_event(). It can detect any newly
created or removed synthetic events.

The new API should be added also in Documentation/libtracefs.txt, the
main man page with all APIs. Forgot to mention that in the previous
review.


Hmm, I see absolutely no tracefs_synth_*() APIs in Documentation/libtracefs.txt.
Maybe this can be fixed in a separate patch.

thanks,
Yordan
