From bd7b1533cd6a68c734062aa69394bec7e2b1718e Mon Sep 17 00:00:00 2001 From: Al Viro Date: Tue, 15 Jul 2008 16:00:59 -0400 Subject: [PATCH] [PATCH] sysctl: make sure that /proc/sys/net/ipv4 appears before per-ns ones Massage ipv4 initialization - make sure that net.ipv4 appears as non-per-net-namespace before it shows up in per-net-namespace sysctls. That's the only change outside of sysctl.c needed to get sane ordering rules and data structures for sysctls (esp. for procfs side of that mess).
