    Argh,. I so disagree. You're doing it backwards.

    First you merge whatever is there, regardless of who came first.

    Then, when everybody doing text modification is using the same
    interface, do a second implementation using a Kconfig knob. If the scary
    new one breaks, no sweat, flip the config. If its proven stable, kill
    off the old one.

    I really don't see why ftrace would be special here.. if you have all
    text_poke() users use the magic new way you'll have more coverage and
    better chances of hitting any snags if there are any.
