Raw Blame History

From 09345f745f894b261bccef694bcd36d79095d2b6 Mon Sep 17 00:00:00 2001
From: Hannes Reinecke <hare@suse.de>
Date: Tue, 29 Apr 2008 16:17:56 +0200
Subject: [PATCH] Remove DEAMON defines
We're now building just one multipath.so library, so any
DAEMON defines are pointless. And we should be setting
the correct dlopen path during compilation.
Signed-off-by: Hannes Reinecke <hare@suse.de>
