[Kasireddy, Vivek] I want these changes to be limited to blob resources only as I do not
know how they might affect other use-cases or whether they are needed there or not. I
don't think I can rely on fd as vfio/display.c also populates the fd field:
    dmabuf = g_new0(VFIODMABuf, 1);
    dmabuf->dmabuf_id  = plane.dmabuf_id;
    dmabuf->buf.width  = plane.width;
    dmabuf->buf.height = plane.height;
    dmabuf->buf.stride = plane.stride;
    dmabuf->buf.fourcc = plane.drm_format;
    dmabuf->buf.modifier = plane.drm_format_mod;
    dmabuf->buf.fd     = fd;

Therefore, I need a way to identify a dmabuf that is associated with blobs vs others.

Thanks,
Vivek
