[lttng-dev] Use lttng for my own module which already has trace events

Hi,

I've developed a kernel module which defines TRACE_EVENTS. These events
are shown in /sys/kernel/debug/tracing/events and i can read them
from /sys/kernel/debug/tracing/trace if they are enabled.

But i want to use these events in lttng. 
# lttng list -k 
does not show them. 

How to make these events available to lttng? Do i need to write a lttng
module? If so, what's the best way to do this for a out of kernel module
which is under the GPL?
