    ftrace: Clean up function probe methods · e67efb93
    Steven Rostedt (Red Hat) authored
    When a function probe is created, each function that the probe is
    attached to, a "callback" method is called. On release of the probe,
    each function entry calls the "free" method.
    First, "callback" is a confusing name and does not really match what
    it does. Callback sounds like it will be called when the probe
    triggers. But that's not the case. This is really an "init" function,
    so lets rename it as such.
    Secondly, both "init" and "free" do not pass enough information back
    to the handlers. Pass back the ops, ip and data for each time the
    method is called. We have the information, might as well use it.
