From 950f4427c2ddc921164088a20f01304cf231437c Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Fri, 16 Feb 2007 01:27:24 -0800 Subject: [PATCH] Add irq flag to disable balancing for an interrupt Add a flag so we can prevent the irq balancing of an interrupt. Move the bits, so we have room for more :) Necessary for the ability to setup clocksources more flexible (e.g. use the different HPET channels per CPU) Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar Cc: john stultz Cc: Roman Zippel Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- kernel/irq/proc.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'kernel/irq/proc.c') diff --git a/kernel/irq/proc.c b/kernel/irq/proc.c index 6d3be06e8ce6..bb44bc995d6e 100644 --- a/kernel/irq/proc.c +++ b/kernel/irq/proc.c @@ -55,7 +55,7 @@ static int irq_affinity_write_proc(struct file *file, const char __user *buffer, cpumask_t new_value, tmp; if (!irq_desc[irq].chip->set_affinity || no_irq_affinity || - CHECK_IRQ_PER_CPU(irq_desc[irq].status)) + irq_balancing_disabled(irq)) return -EIO; err = cpumask_parse_user(buffer, count, new_value); -- cgit v1.2.3-58-ga151
