Hi, guys: My copy of 2.6.17-rc5 has the following code in autostart_array(): mdp_disk_t *desc = sb->disks + i; dev_t dev = MKDEV(desc->major, desc->minor); if (!dev) continue; if (dev == startdev) continue; if (MAJOR(dev) != desc->major || MINOR(dev) != desc->minor) continue; Under what conditions do you think the last if() statement can fire? What is its purpose? This looks like an attempt to detect bit clipping. But what exactly?
