Yeah, we don't currently use it, but it will allow for easier eviction in the future, with -EDEADLK handling
when required. It will currently only annotate the objects as being held by the ww context, which can cause -EDEADLK when other threads try to lock.
Ideally we'd take a ref to the object and perform a blocking lock, but our locking and eviction code can't handle that right now.
