Right, lru_cache_add_anon() is only used by VM code, so it should not be exported. lru_cache_add_file() and lru_cache_add() are supposed to be used by vfs ans fs code. But now only lru_cache_add_file() is used by CIFS and FUSE, which both could be built as module, so it must be exported; and lru_cache_add() has now no module users, so as Rik suggests, it is unexported too.
