Hi Alex,

I've got a cdev v7 candidate in below branch. It has three sub-series per
the suggestion in prior cdev review.

 - cover-letter: Add vfio_device cdev for iommufd support
 - cover-letter: Introduce new methods for verifying ownership in vfio PCI hot reset
 - cover-letter: vfio: Make emulated devices prepared for vfio device cdev

https://github.com/yiliu1765/iommufd/tree/wip/vfio_device_cdev_v7_candidate

However, there is one open on Nicolin's patch in below link. So I need
to wait for it before sending v7.

Regards,
Yi Liu
