From 6e04d01dfa6fe81d6bcae1e85de695285086cee2 Mon Sep 17 00:00:00 2001 From: "Denis V. Lunev" Date: Thu, 10 Jan 2008 03:26:50 -0800 Subject: [PATCH] [NETNS]: Show routing information from correct namespace (fib_hash.c) This is the second part (for the CONFIG_IP_FIB_HASH case) of the patch #4, where we have created proc files in namespaces. Now we can dump correct info in them. Acked-by: Benjamin Thery Acked-by: Daniel Lezcano Signed-off-by: Denis V. Lunev Signed-off-by: David S.
