Grr... Patchwork is not picking patches up.  I have sent an email to
Jeremy Kerr (patchwork admin for ozlabs.org).

I will apply Jake's updated version of the patch to my net-queue and
next-queue trees, but plan to push to Dave net tree.

Alex- can I assume your ACK still stands for this updated change?

Andrew- This has high priority and I would like to see testing
completed in the next day or so, please.
