The last caller to gup_pud_range was removed in commit c2febafc6773 ("mm: convert generic code to 5-level paging"). Mark it as unused to silence a warning from gcc.
Signed-off-by: Chris Packham <chris.pack...@alliedtelesis.co.nz> --- I saw this warning when compiling 4.11-rc2 with -Werror. An equally valid fix would be to remove the function entirely but I went for the less invasive approach. mm/gup.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/mm/gup.c b/mm/gup.c index c74bad1bf6e8..10f5c582273c 100644 --- a/mm/gup.c +++ b/mm/gup.c @@ -1409,8 +1409,9 @@ static int gup_pmd_range(pud_t pud, unsigned long addr, unsigned long end, return 1; } -static int gup_pud_range(p4d_t p4d, unsigned long addr, unsigned long end, - int write, struct page **pages, int *nr) +static int __maybe_unused gup_pud_range(p4d_t p4d, unsigned long addr, + unsigned long end, int write, + struct page **pages, int *nr) { unsigned long next; pud_t *pudp; -- 2.11.0.24.ge6920cf
