Date: Wed, 6 Feb 2008 13:53:31 +0300 From: "Denis V. Lunev" <den@...nvz.org> To: davem@...emloft.net Cc: netdev@...r.kernel.org, devel@...nvz.org, containers@...ts.osdl.org, "Denis V. Lunev" <den@...nvz.org> Subject: [PATCH 11/17] [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.
