From: Petr Tesarik <ptesarik@suse.com>
Date: Tue Oct 6 14:24:14 2015 +0200
Subject: Always create a multipath.conf in kdumprd
References: bsc#948956
Patch-mainline: v0.8.16
Git-commit: 8abf0489c7c647c9b44599e6960e8c1ab0d9f8b6

The configuration file may be missing even if multipath is in use,
but kdump should always create a multipath.conf file that blacklist
all devices except those needed to save the dump (even if none).
