These are often created as a result of the invocation of the driver's ioctl() interface functions, so it is sensible to consider them as being owned by the render context associated with an open drm file. However, at the moment drm_show_memory_stats only traverses the UM-exposed drm objects for which a handle exists. Private driver objects and memory regions, though connected to a render context, are unaccounted for in their fdinfo numbers. Add a new drm_memory_stats 'internal' memory category. Because deciding what constitutes an 'internal' object and where to find these are driver-dependent, calculation of this size must be done through a driver-provided function pointer, which becomes the third argument of drm_show_memory_stats. Drivers which have no interest in exposing the size of internal memory objects can keep passing NULL for unaltered behaviour.
