The perf events are created by the same macro magic as tracefs trace events are. But to hook into perf, it has its own code. It duplicates many of the same macros as the tracefs macros and this is an issue because it misses bug fixes as well as any new enhancements that come with the other trace macros. As the trace macros have been put into their own staging files, have perf take advantage of this and use the tracefs stage 6 macros that the "fast assign" portion of the trace event macro uses.
