    How about this:

    struct ioctl_payload {
    int how_many;
    int* numbers;
    };


    User space sets things up normally, with a valid pointer in 'numbers'.
    Kernel space copy_from_user the structure, then copy_from_user the number's
    memory...

    Can that work? If so, numbers could of course be any data structure we want...
