include/linux/huge_mm.h declares handle_pte_fault inside an ifdef CONFIG_TRANSPARENT_HUGEPAGE; however, mm/memory.c defines the function unconditionally. Move the function outside of the ifdef.
This eliminates a warning from gcc (-Wmissing-prototypes) and from Sparse (-Wdecl). mm/memory.c:3449:5: warning: no previous prototype for ‘handle_pte_fault’ [-Wmissing-prototypes] Signed-off-by: Josh Triplett <[email protected]> --- include/linux/huge_mm.h | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) diff --git a/include/linux/huge_mm.h b/include/linux/huge_mm.h index 3f39803..8ed2187 100644 --- a/include/linux/huge_mm.h +++ b/include/linux/huge_mm.h @@ -55,6 +55,10 @@ extern pmd_t *page_check_address_pmd(struct page *page, extern bool is_vma_temporary_stack(struct vm_area_struct *vma); +extern int handle_pte_fault(struct mm_struct *mm, + struct vm_area_struct *vma, unsigned long address, + pte_t *pte, pmd_t *pmd, unsigned int flags); + #ifdef CONFIG_TRANSPARENT_HUGEPAGE #define HPAGE_PMD_SHIFT HPAGE_SHIFT #define HPAGE_PMD_MASK HPAGE_MASK @@ -87,9 +91,6 @@ extern int copy_pte_range(struct mm_struct *dst_mm, struct mm_struct *src_mm, pmd_t *dst_pmd, pmd_t *src_pmd, struct vm_area_struct *vma, unsigned long addr, unsigned long end); -extern int handle_pte_fault(struct mm_struct *mm, - struct vm_area_struct *vma, unsigned long address, - pte_t *pte, pmd_t *pmd, unsigned int flags); extern int split_huge_page(struct page *page); extern void __split_huge_page_pmd(struct mm_struct *mm, pmd_t *pmd); #define split_huge_page_pmd(__mm, __pmd) \ -- 1.7.10.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
