Date: Mon, 13 Apr 2009 16:56:59 +0800 From: Shen Feng <shen@...fujitsu.com> To: Andrew Morton <akpm@...ux-foundation.org>, David Miller <davem@...emloft.net> CC: linux-kernel@...r.kernel.org Subject: [PATCH] doc: update Documentation/sysctl/net.txt Update Documentation/sysctl/net.txt with the kernel 2.6.29. Move some of the file discriptions from ip-sysctl.txt to net.txt. ip-sysctl.txt only describes the INET(6) parameters. net.txt describes all of the net parameters.
