    I don't know what you've done so far, but can't you simply in
    tracepoint.h define:

    #define TRACE_EVENT_API(a,b,c,d,e) TRACE_EVENT(a,b,c,d,e)

    And every time TRACE_EVENT_API is used, it will simply do whatever
    TRACE_EVENT is at that time?

    I've done similar tricks with other code.
