I guess Kosaki's point is that there may be a disconnect between the
work that is done on the LTTng side and the ftrace side. LTTng uses the
markers as a core infrastructure part (and tracepoints for
instrumentation). I guess his idea is to improve communication, not to
stop it. So by your reaction, I guess his proposal might not be ideal,
but I hear his concerns. I'll try to post the core lttng patchset
shortly.
