Reviewed-by: Matthew Rosato <mjros...@linux.ibm.com> I also ran tests against vfio-pci (mlx, ism, nvme), vfio-ap and vfio-ccw on s390x with an iommufd-enabled host kernel + this series. Testing included having qemu open both fds, passing in one fd and letting qemu open the other, and passing in both fds.
