Hi Eric

actually,I'm working on making the sysctl and data of nf_conntrack proto pernet,
and I think it's necessary,without the pernet proto timeout,we can't control
the container's conntrack timeout unless we change the host's timeout.

maybe somebody want the conntracks in container expired quickly.
So I will keep on doing this job base on your patchset.

what's your comment?

Thanks,
Gao
