This is a rather large patchset that address many pernet issues in the
netfilter codebase, I would classify them in:

1) Patches to prepare the ground for easier pernet integration.

2) Get rid of the dev_net(dev) ? ... : ...; pattern all around the
   netfilter code.

3) Missing pernet sysctl support is some spots, eg. br_netfilter.

4) Pernet hooks, probably the largest changeset in this pile and the
   most important one IMO.

So given that it's quite evident that netfilter netns support is
half-cooked and there's room for improvement in it, as we've been
receiving patches to partially add support on things that people
sporadically needed, could you please split this in several (smaller)
batches in logical changes for easier review?

On a different front, nfnetlink_log and nfnetlink_queue also still
lack of netns support so patches for that would be also appreciated in
another different round.

I'm going to take as much of small preparation patches that I can to
reduce your patchload:

1/43, 8/43, 16/43, 17/43, 18/43, 26/43

Thank you.
