From 9c7b216d23e820e0e148d5be01bbb5bd2d8378fe Mon Sep 17 00:00:00 2001 From: Chandra Seetharaman Date: Tue, 27 Jun 2006 02:54:07 -0700 Subject: [PATCH] cpu hotplug: revert init patch submitted for 2.6.17 In 2.6.17, there was a problem with cpu_notifiers and XFS. I provided a band-aid solution to solve that problem. In the process, i undid all the changes you both were making to ensure that these notifiers were available only at init time (unless CONFIG_HOTPLUG_CPU is defined). We deferred the real fix to 2.6.18. Here is a set of patches that fixes the XFS problem cleanly and makes the cpu notifiers available only at init time (unless CONFIG_HOTPLUG_CPU is defined). If CONFIG_HOTPLUG_CPU is defined then cpu notifiers are available at run time. This patch reverts the notifier_call changes made in 2.6.17 Signed-off-by: Chandra Seetharaman Cc: Ashok Raj Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- kernel/rcupdate.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'kernel/rcupdate.c') diff --git a/kernel/rcupdate.c b/kernel/rcupdate.c index c0e1cb95dd4..a8d80b7048b 100644 --- a/kernel/rcupdate.c +++ b/kernel/rcupdate.c @@ -548,7 +548,7 @@ static void __devinit rcu_online_cpu(int cpu) tasklet_init(&per_cpu(rcu_tasklet, cpu), rcu_process_callbacks, 0UL); } -static int rcu_cpu_notify(struct notifier_block *self, +static int __devinit rcu_cpu_notify(struct notifier_block *self, unsigned long action, void *hcpu) { long cpu = (long)hcpu; -- cgit v1.2.3
