The CREATE_TRACE_POINTS will cause the TRACE_EVENT() macro to define
the functions used for tracing. If you have it defined more than once,
it will either cause a kernel compile error (variables declared more
than once), or if used in modules, will cause confusion (as well as
bloat) because different functions and variables will be defined for
the same tracepoint.

If you need to create a separate file that you can have it defined in a
single place, then please do so!
