[ltt-dev] LLTng probes

[Jyotiswarup Raiturkar]

Hello

 

I'm looking at LTTng working inside the kernel, and trying to understand
the instrumentation.

 

However, I am not able to see how the DEFINE_MARKER_TP() macros and
other probe_* functions in kernel-trace.c are actually used . As I
understand it, to make the actual trace, modules would have to call the
probe_* functions; yet I'm not able to locate these calls.

 

Thanks

Jyoti
