Subject: [PATCH 06/29] sysctl: Implement retire_sysctl_set
Date: Thu, 26 Jan 2012 20:49:47 -0800 [thread overview]
Message-ID: <1327639810-12760-6-git-send-email-ebiederm@xmission.com> (raw)
In-Reply-To: <m1pqe5ah3z.fsf@fess.ebiederm.org>
This adds a small helper retire_sysctl_set to remove the intimate knowledge about
the how a sysctl_set is implemented from net/sysct_net.c
