471  * ioctl time) has completed, the crtc will be reprogrammed to display
472  * that fb after the next vertical refresh.  The ioctl returns
473  * immediately, but subsequent rendering to the current fb will block
474  * in the execbuffer ioctl until the page flip happens.  If a page
475  * flip is already pending as the ioctl is called, EBUSY will be
476  * returned.
477  *
478  * The ioctl supports one flag, DRM_MODE_PAGE_FLIP_EVENT, which will
479  * request that drm sends back a vblank event (see drm.h: struct
480  * drm_event_vblank) when the page flip is done.  The user_data field
481  * passed in with this ioctl will be returned as the user_data field
482  * in the vblank event struct.
