[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). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
