    Stop making crap up.

    If the write fails, the buffer contents have *nothing* to do with what
    is on disk.

    You don't know what the disk contents are.

    So clearly the buffer cannot be up-to-date.

    Now, feel free to use *other* arguments for why we shouldn't clear the
    up-to-date bit, but using the disk contents as one is pure and utter
    garbage. And it is *obviously* pure and utter garbage.
