I hope ftrace people discussio LTTng people more.
AFAIK nobody explain pros. and cons. ftrace against marker approach.
(of cource, LTTng people doen't explain it too)

I believe tracing feature is very important.
too few discussion is sad ;-)

Why nobody try to integrate ftrace and LTTng?
and, Why don't you separate sched-devel tree and ftrace-devel tree?
