From d366f8cbc16882e93538d9a52423c2f50dad7c06 Mon Sep 17 00:00:00 2001 From: Mike Travis Date: Fri, 4 Apr 2008 18:11:12 -0700 Subject: cpumask: Cleanup more uses of CPU_MASK and NODE_MASK * Replace usages of CPU_MASK_NONE, CPU_MASK_ALL, NODE_MASK_NONE, NODE_MASK_ALL to reduce stack requirements for large NR_CPUS and MAXNODES counts. * In some cases, the cpumask variable was initialized but then overwritten with another value. This is the case for changes like this: - cpumask_t oldmask = CPU_MASK_ALL; + cpumask_t oldmask; Signed-off-by: Mike Travis Signed-off-by: Ingo Molnar --- mm/allocpercpu.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'mm/allocpercpu.c') diff --git a/mm/allocpercpu.c b/mm/allocpercpu.c index b0012e27fea8..f4026bae6eed 100644 --- a/mm/allocpercpu.c +++ b/mm/allocpercpu.c @@ -82,9 +82,10 @@ EXPORT_SYMBOL_GPL(percpu_populate); int __percpu_populate_mask(void *__pdata, size_t size, gfp_t gfp, cpumask_t *mask) { - cpumask_t populated = CPU_MASK_NONE; + cpumask_t populated; int cpu; + cpus_clear(populated); for_each_cpu_mask(cpu, *mask) if (unlikely(!percpu_populate(__pdata, size, gfp, cpu))) { __percpu_depopulate_mask(__pdata, &populated); -- cgit v1.2.3
