From 2edf52643d3eb3d13f26d31f9678cf122f2063bc Mon Sep 17 00:00:00 2001 From: Rob Landley Date: Sun, 22 Jan 2006 02:41:51 +0000 Subject: [PATCH] The whole "init is sometimes pid 3" thing is silly. Init is pid 1, anything else is a kernel bug. Both 2.4 and 2.6 should get this right now. This should fix the bug IraquiGeek is seeing (although killall still needs to be fixed.) --- init/halt.c | 24 ++---------------------- init/init.c | 17 ++--------------- init/init_shared.c | 31 +------------------------------ init/poweroff.c | 32 ++------------------------------ init/reboot.c | 32 ++------------------------------ 5 files changed, 9 insertions(+), 127 deletions(-) diff --git a/init/halt.c b/init/halt.c index bfc0042fa..89efdd64a 100644 --- a/init/halt.c +++ b/init/halt.c @@ -4,20 +4,7 @@ * * Copyright (C) 1999-2004 by Erik Andersen * - * This program is free software; you can redistribute it and/or modify - * it under the terms of the GNU General Public License as published by - * the Free Software Foundation; either version 2 of the License, or - * (at your option) any later version. - * - * This program is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
