-From: Hannes Reinecke <hare@suse.de>
-Subject: Disable partitions scan for multipathed devices
-References: bnc#402922,bnc#514767
-
-When multipath devices are being used as disks for VM Guests
-any partition scanning / setup should be done within the VM Guest,
-not from host. So we need to switch off partitions scanning via
-kpartx there.
-For this I've implemented a new feature 'no_partitions' which
-just serves as a notifier to kpartx to _not_ create partitions
-on these devices.
-
-Patch ported to SLES11.
