    Well, someone will have to test it, but NFSv3 explicitly specs 64 bit
    cookies so if linux doesn't support them with NFSv3, linux has a real
    problem.

    In anycase, the NFS protocols haven't changed for UFS exports, since
    UFS uses the file offset in the directory for the cookie.   HAMMER,
    however, uses a hash key + iterator to deal with collisions and needs
    all 64 bits to represent the cookie.
