    And of course the usefulness of such postprocessing tools is gated
    by the ability of users to use them on _any_ kernel they get their
    hands on. Up to this point, this has not been for *any* of the
    existing toolsets, simply because they require the user to either
    recompile his kernel or modify his probe points to match his kernel.
    Until users can actually do without either of these steps (which is
    only possible with static markup) then the development teams of
    the various projects will continue having to invest resources
    chasing the kernel.

    We don't need separate popstprocessing tool teams. The only reasons
    there are separate project teams is because managers in key
    positions made the decision that they'd rather break from existing
    projects which had had little success mainlining and instead use
    their corporate bodyweight to pressure/seduce kernel developers
    working for them into pushing their new great which-aboslutely-
    has-nothing-to-do-with-this-ltt-crap-(no,no, we actually agree
    with you kernel developers that this is crap, this is why we're
    developing this new amazing thing). That's the truth plain and
    simple.

    When I started involving myself in Linux development a decade ago,
    I honestly did not think I'd ever see this kind of stuff happen,
    but, hey, that's life.
