Support for network namespaces in mainline is pretty complete for

Ben your patchset is completely inappropriate.

Temporarily adding elements to the ABI that we intend to remove
is not a proper solution to this problem.

In fact, I feared that would be an issue before I sent the patches.
Thanks for confirming this.

But, as this alternative was discussed a bit after Al's comments on your
last patches, I had to give it a try and code a proof-of-concept.


That user space visible ida you add is a namespace identifier that breaks
nested containers and migration. It is very very very wrong.
