Whoops, sorry, I haven't been paying attention.  Do you have a pointer
to documentation?  I'm unclear what the actual concurrency change
is--sounds like it becomes possible that e.g. multiple ->init methods
(from the same pernet_operations but for different namespaces) could run
in parallel?

Sounds likely to be safe, and I don't actually care too much who merges
them as they look very unlikely to conflict with anything pending.  But
unless anyone tells me otherwise I'll take the one nfsd_net_ops patch
and leave the rest to Anna or Trond.
