Paolo ackd the main nbd series, so we're just waiting for the CLI
patch series it depends on

  https://lists.gnu.org/archive/html/qemu-devel/2016-02/msg00296.html

In terms of merging the NBD series, the bare minimum is the qom patch
and the --object arg support. I could rebase the NBD series to just
include those two directly, since they're basically ready:

  https://lists.gnu.org/archive/html/qemu-devel/2016-02/msg00297.html
  https://lists.gnu.org/archive/html/qemu-devel/2016-02/msg00302.html

Eric ACK'd the second one, and the fixes for the first one were
trivial.

Regards,
Daniel
