    Hm, as this patch changes the UIO userspace/kernelspace interface, how
    about also documenting it in the existing UIO documentation so that
    people know it is there, and so that we can properly review if it is a
    sane change.

    ALso, for kernel/user api changes, you should cc: the mailing list so that it can be reviewed there
    by the people trying to maintain the kernel documentation.
