NBD can become contended on its single connection.  We have to serialize all

Idea is that it can now use multiple CPUs concurrently...?

Do you have a diff for the nbd-server, too?

nbd-server doesn't need anything special, it just works. I have a patch for nbd-client so you can open multiple connections to setup the NBD device. You can find my patches for the userspace stuff here

Thanks,
