What:		 /sys/.../<device>/vfio-dev/vfioX/
Date:		 September 2022
Contact:	 Yi Liu <yi.l.liu@intel.com>
Description:
		 This directory is created when the device is bound to a
		 vfio driver. The layout under this directory matches what
		 exists for a standard 'struct device'. 'X' is a unique
		 index marking this device in vfio.
vfio: Add struct device to vfio_device and replace kref. With it a 'vfio-dev/vfioX' node is created under the sysfs path of the parent, indicating the device is bound to a vfio driver, e.g.: /sys/devices/pci0000\:6f/0000\:6f\:01.0/vfio-dev/vfio0 It is also a preparatory step toward adding cdev for supporting future device-oriented uAPI.
