    The "write less than a full block to the end of the file" is actually
    a reasonably common case.

    It may not make for a great filesystem benchmark, but it also isn't
    actually insane. People who do logging in user space do this all the
    time, for example. And it is *not* stupid in that context. Not at all.

    It's never going to be the *main* thing you do (unless you're AIM),
    but I do think it's worth fixing.

    And AIM7 remains one of those odd benchmarks that people use. I'm not
    quite sure why, but I really do think that the normal "append smaller
    chunks to the end of the file" should absolutely not be dismissed as
    stupid.
