Sure. Looks like we have misunderstanding here. When I said, that Lockd should 
be one for all, I meaned, that we will have only one kthread for all ns (not one 
per ns). Private data will be per net ns, of course.

BTW, Bruce, please, have a brief look at my e-mail to linux-nfs@...r.kernel.org 
named "SUNRPC: non-exclusive pipe creation".
I've done a lot in "RPC pipefs per net ns" task, and going to send first patches 
soon. But right now I'm really confused will this non-exclusive pipes creation 
and almost ready so remove this functionality. But I'm afraid, that I've missed 
something. Would be greatly appreciate for your opinion about my question.
