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?
