From e9a81a821d7f9c5d899cc3acdeafbd884c2c48bb Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Tue, 26 Oct 2010 14:22:01 -0700 Subject: rmap: wrap page_check_address() using __cond_lock() The page_check_address() conditionally grabs *@ptlp in case of returning non-NULL. Rename and wrap it using __cond_lock() removes following warnings from sparse: mm/rmap.c:472:9: warning: context imbalance in 'page_mapped_in_vma' - unexpected unlock mm/rmap.c:524:9: warning: context imbalance in 'page_referenced_one' - unexpected unlock mm/rmap.c:706:9: warning: context imbalance in 'page_mkclean_one' - unexpected unlock mm/rmap.c:1066:9: warning: context imbalance in 'try_to_unmap_one' - unexpected unlock Signed-off-by: Namhyung Kim Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- mm/rmap.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'mm/rmap.c') diff --git a/mm/rmap.c b/mm/rmap.c index 0995a8f6886..bfeffbddb71 100644 --- a/mm/rmap.c +++ b/mm/rmap.c @@ -409,7 +409,7 @@ unsigned long page_address_in_vma(struct page *page, struct vm_area_struct *vma) * * On success returns with pte mapped and locked. */ -pte_t *page_check_address(struct page *page, struct mm_struct *mm, +pte_t *__page_check_address(struct page *page, struct mm_struct *mm, unsigned long address, spinlock_t **ptlp, int sync) { pgd_t *pgd; -- cgit v1.2.3
