3.0-stable review patch. If anyone has any objections, please let me know.
------------------ From: Steven Rostedt <[email protected]> commit 072126f4529196f71a97960248bca54fd4554c2d upstream. Currently, if set_ftrace_filter() is called when the ftrace_ops is active, the function filters will not be updated. They will only be updated when tracing is disabled and re-enabled. Update the functions immediately during set_ftrace_filter().
