The huge_pte_offset() returns a pte_t *, not an integer so when huge-tlb is off, the replacement inline macro should return a pte_t * too. This fixes the following sparse warning: mm/page_vma_mapped.c:156:29: warning: Using plain integer as NULL pointer Signed-off-by: Ben Dooks <ben.dooks@xxxxxxxxxxxxxxx> --- Cc: Mike Kravetz <mike.kravetz@xxxxxxxxxx> Cc: linux-mm@xxxxxxxxx Cc: linux-kernel@xxxxxxxxxxxxxxx --- include/linux/hugetlb.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/include/linux/hugetlb.h b/include/linux/hugetlb.h index 53fc34f930d0..e42c76aa1577 100644 --- a/include/linux/hugetlb.h +++ b/include/linux/hugetlb.h @@ -185,7 +185,7 @@ static inline void hugetlb_show_meminfo(void) #define hugetlb_free_pgd_range(tlb, addr, end, floor, ceiling) ({BUG(); 0; }) #define hugetlb_mcopy_atomic_pte(dst_mm, dst_pte, dst_vma, dst_addr, \ src_addr, pagep) ({ BUG(); 0; }) -#define huge_pte_offset(mm, address, sz) 0 +#define huge_pte_offset(mm, address, sz) (pte_t *)NULL static inline bool isolate_huge_page(struct page *page, struct list_head *list) { -- 2.23.0
