From: Denis V. Lunev Date: Fri, 29 Feb 2008 04:50:33 +0000 (-0800) Subject: [IPV4]: rt_cache_get_next should take rt_genid into account. X-Git-Tag: v2.6.26-rc1~1138^2~562 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=642d6318119af60ac019524bd4edcfbd19d9d211;p=linux-2.6-omap-h63xx.git [IPV4]: rt_cache_get_next should take rt_genid into account. In the other case /proc/net/rt_cache will look inconsistent in respect to genid. Signed-off-by: Denis V. Lunev Acked-by: Alexey Kuznetsov Signed-off-by: David S.
