(1) Fix a bunch of warnings from sparse, including missing RCU bits and kdoc-function argument mismatches (2) Implement a keyctl to allow a key to be moved from one keyring to another, with the option of prohibiting key replacement in the destination keyring. (3) Grant Link permission to possessors of request_key_auth tokens so that upcall servicing daemons can more easily arrange things such that only the necessary auth key is passed to the actual service program, and not all the auth keys a daemon might possesss. Changes: I made the change you suggested on patch 6 and added the reviewed-by's to patches 1-5 and 7.
