    This particular case was intentional: -ENOMEM really is the right return
    code when the ring cannot be allocated. Mixing it up with the potential
    return codes from do_mmap or other functions might result in a very
    nonsensical return. Perhaps someone can provide an arguement in favour
    of propagating the value, but I think it really can only mean "you asked
    the kernel to allocate too much memory or did something stupidly buggy with
    threads". Cheers,
