From 95bdfccb2bf4ea21c0065772c6a2c75cbaf6ad0d Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Fri, 30 Nov 2007 23:55:42 +1100 Subject: [NET]: Implement the per network namespace sysctl infrastructure The user interface is: register_net_sysctl_table and unregister_net_sysctl_table. Very much like the current interface except there is a network namespace parameter. With this any sysctl registered with register_net_sysctl_table will only show up to tasks in the same network namespace. All other sysctls continue to be globally visible. Signed-off-by: Eric W.
