Indeed.
Rainer, while your desire to keep CONFIG_NET_NS=n case equivalent
to current code is understandable and kernel people share it at large,
what you're fighting for is maybe one dereference on speed-uncritical
code paths and one pointer in small amount of data structures.
As such having common executable code matters more.
netns will be stubbed to &init_net at several places.
See how e. g. xt_hashlimit is done.
