    Something is wrong with your kernel build.

    I suspect that you have built your kernel but not your module with
    CONFIG_MODVERSIONS.

    With the exception of a couple of these which I don't recognise,
    these should definitely all be exported.

    You can't make a useful modular filesystem without importing
    register_filesystem :-)
