netfilter: netns nf_conntrack: per-netns expectations
Make per-netns a) expectation hash and b) expectations count. Expectations always belongs to netns to which it's master conntrack belong. This is natural and doesn't bloat expectation. Proc files and leaf users are stubbed to init_net, this is temporary. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Patrick McHardy <kaber@trash.net>
