Note, the CREATE_TRACE_POINTS must only be done in one location. Not
every place. It creates the code that does the work to make the
tracepoints show up in /debug/tracing/events/* as well as the callback
code and other such things. If you define it in more than one .c file,
then you will have linker issues due to the functions being created more
than once.
