[PATCH] vmsplice.2: vmsplice() does not fail on nr_segs=0

[Cyril Hrubis <metan-+ZI9xUNit7I@public.gmane.org>]

This case is no-op and no error is returned.

See fs/splice.c vmsplice syscall which contains:

        if (unlikely(nr_segs > UIO_MAXIOV))
                return -EINVAL;
        else if (unlikely(!nr_segs))
                return 0;

and looking at the git log suggests that this snipped was always there.
