Subject: [PATCH 4/4] kernel: doc: remove outdated comment cred.c
Date: Tue, 10 Mar 2020 14:44:18 +0100 [thread overview]
Message-ID: <AM6PR03MB517039DB07AB641C194FEA57E4FF0@AM6PR03MB5170.eurprd03.prod.outlook.com> (raw)
In-Reply-To: <877dzt1fnf.fsf@x220.int.ebiederm.org>
This removes an outdated comment in prepare_kernel_cred.
There is no "cred_replace_mutex" any more, so the comment must
go away.
