 Usage:
 	Be sure that you have CONFIG_FUNCTION_TRACER
-	# mkdir /debugfs
-	# mount -t debug debug /debug
-	# echo function > /debug/tracing/current_tracer
-	$ cat /debug/tracing/trace_pipe > ~/raw_trace_func
+	# mount -t debugfs nodev /sys/kernel/debug
+	# echo function > /sys/kernel/debug/tracing/current_tracer
+	$ cat /sys/kernel/debug/tracing/trace_pipe > ~/raw_trace_func
 	Wait some times but not too much, the script is a bit slow.
 	Break the pipe (Ctrl + Z)
