Honestly, I hate that flag. Most people don't even know about it. It was added in the beginning of ftrace as a way to stop function tracing in the latency tracer. But that use case has been obsoleted by 328df4759c03e ("tracing: Add function-trace option to disable function tracing of latency tracers"). I may just remove the damn thing and only add it back if somebody complains about it.
