Hmm, now you have argsz and flags twice in vfio_vgpu_dmabuf_info ...
I think we should have something like this:
struct

I think we should have something like this:
struct
Here we defined a new ioctl to create a fd for a vfio device based on
the input type. Now only one type is supported that is a dma-buf
management fd.
Two ioctls are defined for the dma-buf management fd: query the vfio
vgpu's plane information and create a dma-buf for a plane.
