Hello,

I am following trace/tracepoints.txt guide to add some tracepoints to
already existing kernel module.

I've created include/trace/events/mysubsys.h
and added

#include <trace/events/mysubsys.h>

#define CREATE_TRACE_POINTS
DEFINE_TRACE(mysubsys_event1);
EXPORT_TRACEPOINT_SYMBOL_GPL(mysubsys_event1);

to the module sources. There are symbols *_mysubsys_event1 in module ko
file.

The issue is that I don't see my events in /sys/kernel/debug/tracing/events
Not even ./mysubsys path here.
