The encoding for plexes and subdisks no longer reflects the object to which they belong. The super devices are high-order volume numbers. This gives vastly more potential volumes (4 million instead of 256). As a result of the minor number changes, split out the superdevice handling into a separate function, vinum_super_ioctl. This was most of the code of vinumioctl. attachobject: Improve error checking. END
