   The Google Summer of Code LTTng entry (http://bugs.lttng.org/projects/lttng/wiki/Google_Summer_of_Code_2013) is a promising initiative.  May I propose another little project idea?

Babeltrace support for the debugfs (/sys/kernel/debug/tracing) trace format

Brief explanation:
Provide a Babeltrace plug-in to allow Babeltrace to read from traces created by the debugfs service (/sys/kernel/debug/tracing/trace).

Expected results: A Babeltrace plug-in, tests, examples and documentation.

Skill level: Easy - Medium

Prerequisite Knowledge: C, OO development

Mentors: ?

   Even if the debugfs tracing facility is destined for eventual withdrawal from the Linux kernel, it may be of interest to some to recover older traces generated in this way -if only in order to be able to process them in the same way as CTF text dumps.  Conversion to the babeltrace text format should be fairly straightforward; conversion to CTF would be trickier.

   Is this idea worthwhile or worthless?
