From 1597fbc0faf88c42edb3fe42e92e53b83c3f120e Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Sat, 1 Dec 2007 23:51:01 +1100 Subject: [UNIX]: Make the unix sysctl tables per-namespace This is the core. * add the ctl_table_header on the struct net; * make the unix_sysctl_register and _unregister clone the table; * moves calls to them into per-net init and exit callbacks; * move the .data pointer in the proper place.
