From d6e2e5a35418a624cabcd792257508f18bd7725b Mon Sep 17 00:00:00 2001 From: Hannes Reinecke <hare@suse.de> Date: Tue, 24 Feb 2009 14:13:56 +0100 Subject: [PATCH] Fixup multibus zero-path handling The 'multibus' pgpolicy function currently always adds a pathgroup, even when no paths are present. This confuses setup_map() which doesn't expect this behaviour.
