The logic that it follows to split changes into patches is not correct. This breaks the compilation of my tree since patch 2 until the entire patchset is applied. This has to start by one patch that adds the basic infrastructure to register the layer 3 and 4 conntrack timeout per-net support and it prepares the per-protocol per-net support. This implies to propagate the minimal set of changes to make sure it compiles, ie. modify clients to use the new interface to register init_net. Then, follow-up per-protocol patches that use the new infrastructure implement the per-protocol support. All this without breaking the compilation of my tree between patches. I'm all for fixing the existing unfinished container support for Netfilter, but this needs to be done appropriately. -- 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
