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@vger.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.
