If that is all you need we could do a flush_workqueue(nbd->recv_workq)
(you would need Jens's for next branch which has some work queue changes
in nbd).

Yeah, this makes sense.

This has already been done in nbd_disconnect_and_put() in the Jen's for next branch code. So here it will make no sense.

I will rebase this patch set to that branch.
