Don't try to dump the index key that distinguishes an object if netfs data in the cookie the object refers to has been cleared (ie. the cookie has passed most of the way through __fscache_relinquish_cookie()). Since the netfs holds the index key, we can't get at it once the ->def and ->netfs_data pointers have been cleared - and a NULL pointer exception will ensue, usually just after a: CacheFiles: Error: Unexpected object collision error is reported.
