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.
