strncpy again in xen

I know I'm repeating myself.. strncpy must always be explicitly NULL terminated. Here is another example from xen (utils)

static int get_name(int argc, char *argv[], char *name)
{
    ssize_t len = strlen(argv[0]);
    if ( len > XEN_LIVEPATCH_NAME_SIZE )
    {
        fprintf(stderr, "ID must be no more than %d characters.\n",
                XEN_LIVEPATCH_NAME_SIZE);
        errno = EINVAL;
        return errno;
    }
    /* Don't want any funny strings from the stack. */
    memset(name, 0, XEN_LIVEPATCH_NAME_SIZE);
    strncpy(name, argv[0], len);
    return 0;
}

There are a few other places in xen too..
