-From: Hannes Reinecke <hare@suse.de>
-Subject: Emulate BLKRRPART on device-mapper
-
-Partitions on device-mapper devices are managed by kpartx (if at
-all). So if we were just to send out a 'change' event if someone
-called BLKRRPART on these devices, kpartx will be triggered via udev
-and can manage the partitions accordingly.
