--- Comment #22 from Jeffrey A. Law <law at redhat dot com> 2013-01-20 06:16:21 UTC --- I must have been looking at something else; the 4.6 and trunk loops are effectively the same, so this is no longer a regression. We might will want the fwprop patch, so I've attached this to the 4.9 pending patches meta bug.
