From: "Steven Rostedt (VMware)" There are no users of unregister_ftrace_function_probe_all(). The only probe function that is used is unregister_ftrace_function_probe_func(). Rename the internal static function __unregister_ftrace_function_probe() to unregister_ftrace_function_probe_func() and make it global. Also remove the PROBE_TEST_FUNC as it would be always set.
