cases that kernel module uses lttng to trace its own code

cases that kernel module uses lttng to trace its own code

[yin sun]

Hello,

Is there any example that a loadable kernel module utilize lttng
tracepoint to trace its own code. Not those ready made probes.

In this case, what minimal lttng modules do I have to load?

Thanks,
/Yin

I guess you'll want to go by trial and error, and also the lsmod
dependency information can help out.

Good luck!
