From 528c4ceb427dad4a3893ba3d1913782efae0cd0e Mon Sep 17 00:00:00 2001 From: "Denis V. Lunev" Date: Thu, 13 Dec 2007 09:45:12 -0800 Subject: [PATCH] [IPV6]: Always pass a valid nl_info to inet6_rt_notify. This makes the code in the inet6_rt_notify more straightforward and provides groud for namespace passing. Signed-off-by: Denis V. Lunev Signed-off-by: David S.
