- (*) int (*duplicate)(struct key *key, const struct key *source);

- If this type of key can be duplicated, then this method should be
- provided. It is called to copy the payload attached to the source into the
- new key. The data length on the new key will have been updated and the
- quota adjusted already.
-
- This method will be called with the source key's semaphore read-locked to
- prevent its payload from being changed, thus RCU constraints need not be
- applied to the source key.
-
- This method does not have to lock the destination key in order to attach a
- payload. The fact that KEY_FLAG_INSTANTIATED is not set in key->flags
- prevents anything else from gaining access to the key.

(*) int (*update)(struct key *key, const void *data, size_t datalen);
