Thanks.

My fingers rebelled, and struct net seems to be sufficiently descriptive.
However that is a cosmetic detail and if there is a general consensus
that renaming it to be struct netns or whatever would be a more
readable/maintainable name I can change it.

The practical issue at this point in the cycle is visibility.  With a
kmem cache it is easy to spot ref counting leaks or other problems
if they happen.  Without it debugging is much more difficult.  While I
am touched with your faith in my ability to write perfect patches I
think it makes a lot of sense to keep the cache at least until
sometime after the network namespace code is merged and people
generally have confidence in the implementation.
