50  * @ref_hash: Hash tables of ref objects, one per ttm_ref_type,
51  * for fast lookup of ref objects given a base object.
94  * @head: List entry for the per-file list of ref-objects.
96  * @kref: Ref count.
98  * @obj: Base object this ref object is referencing.
100  * @ref_type: Type of ref object.
105  * a particular ttm_object_file. It also carries a ref count to avoid creating
106  * multiple ref objects if a ttm_object_file references the same base
