commit 91b9ef5a1cf36c8420f85aa45daa8239384453dd
Author: Hannes Reinecke <hare@suse.de>
Date:   Fri Mar 20 10:30:04 2009 +0100

Increase priority value for emc priority callout
    
    For non-default paths the emc priority callout should
    not return '0', as this will inhibit the daemon to switch
    paths.
