You'll have to dig the old LTTng 0.x kernel tracer series (see legacy on
the website). Good luck with that, as it is not supported anymore.

Yes, the user-space tracing part is kernel-independent and
lttng-modules-independent. However, you will not be able to control the
old lttng 0.x kernel tracer with the lttng 2.0 control tools.

Good luck!
