Yeah, if you can just make sure to add an equivalent patch for nvme-pci,
otherwise the last patch in this series will deadlock it.

Some experiments I've run over the last day have me convinced no one is
actually hitting queue count changes in nvme-pci, so I'm not concerned
with opening that race to this scenario. You'd get IO errors either way;
your proposal just potentially gives you more of them, but I don't think
encountering that is practical reality right now anyway.
