From 8100fe56f1d249afbb0232ac0a8ee6d598ad9e5f Mon Sep 17 00:00:00 2001 From: wartens2 Date: Thu, 24 Apr 2008 17:07:56 +0000 Subject: [PATCH] Make sure that when calling __vmem_alloc that we do not have __GFP_ZERO set. Once the memory is allocated then zero out the memory if __GFP_ZERO is passed to __vmem_alloc. git-svn-id: https://outreach.scidac.gov/svn/spl/trunk@88 7e1ea52c-4ff2-0310-8f11-9dd32ca42a1c --- include/sys/kmem.h | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/include/sys/kmem.h b/include/sys/kmem.h index 7af10f9a4554..a02bdcbffe71 100644 --- a/include/sys/kmem.h +++ b/include/sys/kmem.h @@ -72,14 +72,17 @@ extern int kmem_warning_flag; \ ASSERT(flags & KM_SLEEP); \ \ - _ptr_ = (void *)__vmalloc((size), ((flags) | \ - __GFP_HIGHMEM), PAGE_KERNEL); \ + _ptr_ = (void *)__vmalloc((size), (((flags) | \ + __GFP_HIGHMEM) & \ + ~__GFP_ZERO), PAGE_KERNEL); \ if (_ptr_ == NULL) { \ printk("spl: Warning vmem_alloc(%d, 0x%x) failed at %s:%d " \ "(%ld/%ld)\n", (int)(size), (int)(flags), \ __FILE__, __LINE__, \ atomic64_read(&vmem_alloc_used), vmem_alloc_max); \ } else { \ + if (flags & __GFP_ZERO) \ + memset(_ptr_, 0, (size)); \ atomic64_add((size), &vmem_alloc_used); \ if (unlikely(atomic64_read(&vmem_alloc_used)>vmem_alloc_max)) \ vmem_alloc_max = atomic64_read(&vmem_alloc_used); \
