thank you. I would like to take some time this weekend
to understand why v1 of your patch hit the null rtn,
but v2 did not (a superficial glance at the patch suggested
that you were registering twice in both cases, with just
a reordering, so I would like to understand the root-cause of
the null ptr deref with v1)

As for registering 2 times, that needs some comments to
provide guidance for other subsystems. e.g., I found the
large block comment in net-namespace.h very helpful, so lets
please clearly document what and why and when this should
be used.
