What git tree is that?
I'm trying to work off Pablo's nf-next tree (for my IPVS changes):
git://1984.lsi.us.es/nf-next
But I don't see the patch in that tree ...yet.
Notice, the bug is also present in DaveM's net-next tree.
(I know I stated earlier that it didn't affect net-next, but I just
forgot to select the new netfilter .config options for nat)
