+Under some circumstances, it may be desirable to desirable to deal with a
+bundle of keys.  The facility provides access to the keyring type for managing
+such a bundle:
+
+       struct key_type key_type_keyring;
+
+This can be used with a function such as request_key() to find a specific
+keyring in a process's keyrings.  A keyring thus found can then be searched
+with keyring_search().  Note that it is not possible to use request_key() to
+search a specific keyring, so using keyrings in this way is of limited utility.
