    Here's the actual code, I typoed this first time.
    /* count partitions 1 to 15 with sizes > 0 */
    for(i=1; i <MAX_PART; i++) {
    if (!disk->part[i])
    continue;
    if (disk->part[i]->nr_sects != 0)
    luninfo.num_parts++;
    We're trying to figure how many partitions are physically on the disk. We do
    this for one of our utilities. Is there a kernel API that will return this
    data for us?
