Yep, it is only a 2.6.32 kernel which is concerned by this modification.
What I meant is the kernel team just disabled the netns with an update 
in 2.6.32

That looked very weird for me. I tried to convince them the netns was 
needed but they decided to remove a kernel feature in a kernel update. :s
