The obj->stolen is currently used to identify an object allocated from stolen memory. This dates back to when there were just 1.5 types of objects, an object backed by shmemfs and an object backed by shmemfs with a contiguous physical address. Now that we have several different types of objects, we no longer want to treat stolen objects as a special case.
