File libparted-partition-naming.patch of Package parted

From: Petr Uzel <petr.uzel@suse.cz>
Subject: libparted: Change partition naming for SUSE needs
References: bsc#1056508
Patch-mainline: no, custom SUSE patch

Device mapper partitions always use the suffix "-part%d" for
partition names. Other devices with a trailing number in their
name use the "p%d" suffix. All other devices use the "%d" suffix.

YaST depends on this.

[mwilck: Fixed dm part name in _dm_add_partition(), bsc#1056508]
[sparschauer: Fixed dm part name in _dm_resize_partition(), bsc#1056508]
[sparschauer: Wrote the patch description]
[sparschauer: Dropped "_part" suffix, bsc#1078820, bsc#1081547]
