I'm going to place this series in the nf-next tree, thanks! If there's some fallout, please send me an incremental fix. > The changes are also available against net-next at: > git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/net-next.git master > > My entire pending set of changes for those who want to look ahead is at: > git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/net-next.git for-testing I can see quite a lot of changes for IPVS. I'd suggest you route IPVS changes through ipvs-devel mailing list so Simon picks them from there. Will be preparing a batch with Netfilter updates for net-next to pass up to David asap. -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
