    I meant nchunks=2, nleft=0. Btw, the value you reported could occur only
    if the userspace passed nfds=2G-512,2G-511,...,2G-1, but that should have
    been caught by the clause:

    if (nfds > current->files->max_fds)
    return -EINVAL;

    So, it is still an open problem; I will try to see what may go wrong but
    any extra data (especially strace output containing calls to poll(2))
    would help greatly.
