From mboxrd@z Thu Jan 1 00:00:00 1970 From: "Eric W. Biederman" Subject: [PATCH 10/29] sysctl: Add ctl_table chains into cstring paths Date: Thu, 26 Jan 2012 20:49:51 -0800 Message-ID: <1327639810-12760-10-git-send-email-ebiederm@xmission.com> References: Cc: , , Damien Millescamps , "Eric W. Biederman" To: Return-path: In-Reply-To: Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org For any component of table passed to __register_sysctl_paths that actually serves as a path, add that to the cstring path that is passed to __register_sysctl_table. The result is that for most calls to __register_sysctl_paths we only pass a table to __register_sysctl_table that contains no child directories. Signed-off-by: Eric W.
