Detailed Description

struct ttm_ref_object

: Hash entry for the per-file object reference hash.

: List entry for the per-file list of ref-objects.

: Ref count.

: Base object this ref object is referencing.

: Type of ref object.

This is similar to an idr object, but it also has a hash table entry that allows lookup with a pointer to the referenced object as a key. In that way, one can easily detect whether a base object is referenced by a particular ttm_object_file. It also carries a ref count to avoid creating multiple ref objects if a ttm_object_file references the same base object more than once.
