I really don't want to do that. Then I would need to show

 # echo function_graph > /sys/kernel/debug/current_trace

Which I really do not like. I state that the common place to mount it is 
in /sys/kernel/debug, But my examples are much easier to understand if
I just do: # echo function_graph > /debug/current_trace
