I don't have a problem with the idea of this patch. My concern is that
the code in lib/traceevent will soon be obsoleted by using the
libtraceevent library in the Linux kernel under tools/lib/traceevent.
That means when we transition to the libtraceevent library, this work
will be lost.
Instead, could this be added to tools/lib/traceevent in the Linux
kernel somehow, and instead of building it into the executable, perhaps
make it part of the libtraceevent.a file (the static version of the
libary).
Thoughts?
