    ftrace: Allow subops filtering to be modified · d9bbfbd1
    Steven Rostedt (Google) authored
    The subops filters use a "manager" ops to enable and disable its filters.
    The manager ops can handle more than one subops, and its filter is what
    controls what functions get set. Add a ftrace_hash_move_and_update_subops()
    function that will update the manager ops when the subops filters change.
