	* that fb after the next vertical refresh. The ioctl returns

	* flip is already pending as the ioctl is called, EBUSY will be

	* The ioctl supports one flag, DRM_MODE_PAGE_FLIP_EVENT, which will
	* request that drm sends back a vblank event (see drm.h: struct
	* drm_event_vblank) when the page flip is done. The user_data field
	* passed in with this ioctl will be returned as the user_data field
	* in the vblank event struct.

	* clever to use it for.
