From: Haibo Li <haibo.li@xxxxxxxxxxxx> commit 4f572f0074b8be8a70bd150d96a749aa94c8d85f upstream. When tools/testing/selftests/mm/gup_test.c is compiled as 32bit, then run on arm64 kernel, it reports "ioctl: Inappropriate ioctl for device". Fix it by filling compat_ioctl in gup_test_fops Link: https://lkml.kernel.org/r/20230526022125.175728-1-haibo.li@xxxxxxxxxxxx Signed-off-by: Haibo Li <haibo.li@xxxxxxxxxxxx> Acked-by: David Hildenbrand <david@xxxxxxxxxx> Cc: AngeloGioacchino Del Regno <angelogioacchino.delregno@xxxxxxxxxxxxx> Cc: Matthias Brugger <matthias.bgg@xxxxxxxxx> Cc: John Hubbard <jhubbard@xxxxxxxxxx> Cc: <stable@xxxxxxxxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- mm/gup_test.c | 1 + 1 file changed, 1 insertion(+) --- a/mm/gup_test.c +++ b/mm/gup_test.c @@ -381,6 +381,7 @@ static int gup_test_release(struct inode static const struct file_operations gup_test_fops = { .open = nonseekable_open, .unlocked_ioctl = gup_test_ioctl, + .compat_ioctl = compat_ptr_ioctl, .release = gup_test_release, };
