Could use a changelog.

Ming: does this solve your problem of not seeing the new queues
after a qemu CPU hotplug + reset?

The issue I observed is that there isn't NVMe reset triggered after
CPU becomes online.

This won't help with that.

It may take a while since the test need to apply the whole patchset.
Or is it fine to figure out one fix on this issue? Sagi?

No need, all this doesn't even touch pci for now...
