From 0f3c2a89c1451cdf6328f99977bd9decd4f708e1 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Sun, 8 Feb 2009 16:18:03 -0800 Subject: irq: clear kstat_irqs Impact: get correct kstat_irqs [/proc/interrupts] for msi/msi-x etc need to call clear_kstat_irqs(), so when we reuse that irq_desc, we get correct kstat in /proc/interrupts. This makes /proc/interrupts not have entries. Don't need to worry about arch that doesn't support genirq, because they will not call dynamic_irq_cleanup(). v2: simplify and make clear_kstat_irqs more robust Signed-off-by: Yinghai Lu Signed-off-by: Ingo Molnar --- kernel/irq/internals.h | 1 + 1 file changed, 1 insertion(+) (limited to 'kernel/irq/internals.h') diff --git a/kernel/irq/internals.h b/kernel/irq/internals.h index e6d0a43..b60950b 100644 --- a/kernel/irq/internals.h +++ b/kernel/irq/internals.h @@ -15,6 +15,7 @@ extern int __irq_set_trigger(struct irq_desc *desc, unsigned int irq, extern struct lock_class_key irq_desc_lock_class; extern void init_kstat_irqs(struct irq_desc *desc, int cpu, int nr); +extern void clear_kstat_irqs(struct irq_desc *desc); extern spinlock_t sparse_irq_lock; extern struct irq_desc *irq_desc_ptrs[NR_IRQS]; -- cgit v1.1
