[PATCH] Add format modifier for devfs like naming

Anyone want to verify this or not? I would prefer to have the ability of creating partition nodes in devfs style built-in to udev. Devfs used to call the whole disk e.g. "/dev/dasd/0123/disk" and the partitions "/dev/dasd/0123/part[1-3]". This can obviously be done with a CALLOUT rule, but its common enough to make it a format modifier. AFAIK, this scheme has been used for ide, scsi and dasd disks, which is about 99% of all disks ever connected to Linux.
