Re: [PATCH 2/5] net: Make rtnetlink infrastructure network namespace aware

I'm wondering why this receive queue processing on unlock is still
necessary today, we don't do trylock in rtnetlink_rcv anymore, so
all senders will simply wait until the lock is released and then
process the queue.

Good question, I should probably look.  I was lazy and didn't go back
and audit why we were doing this.  I just coded a routine that I was
certain would work.  It does appear that we are processing the queue
with sk_data_read when we add a message, so this may be completely
unnecessary.  I will go back and look.  If we can remove this bit
things should be simpler.
