From b8e1f9b5c37e77cc8f978a58859b35fe5edd5542 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Sat, 8 Dec 2007 00:12:33 -0800 Subject: [NET] sysctl: make sysctl_somaxconn per-namespace Just move the variable on the struct net and adjust its usage. Others sysctls from sys.net.core table are more difficult to virtualize (i.e. make them per-namespace), but I'll look at them as well a bit later.
