If anyone has any objections, please let me know. ------------------ commit 7cfad65297bfe0aa2996cd72d21c898aa84436d9 upstream. The return value of sizeof() is of type size_t, so we must print it using the %z format modifier rather than %l to avoid this warning on some architectures: fs/btrfs/tree-checker.c: In function 'check_dir_item': fs/btrfs/tree-checker.c:273:50: error: format '%lu' expects argument of type 'long unsigned int', but argument 5 has type 'u32' {aka 'unsigned int'} [-Werror=format=] Fixes: 005887f2e3e0 ("btrfs: tree-checker: Add checker for dir item") Signed-off-by: Arnd Bergmann Reviewed-by: David Sterba Signed-off-by: David Sterba Signed-off-by: Ben Hutchings Signed-off-by: Sasha Levin --- fs/btrfs/tree-checker.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/fs/btrfs/tree-checker.c b/fs/btrfs/tree-checker.c index b32df86de9bf..9376739a4cc8 100644 --- a/fs/btrfs/tree-checker.c +++ b/fs/btrfs/tree-checker.c @@ -223,7 +223,7 @@ static int check_dir_item(struct btrfs_root *root, /* header itself should not cross item boundary */ if (cur + sizeof(*di) > item_size) { dir_item_err(root, leaf, slot, - "dir item header crosses item boundary, have %lu boundary %u", + "dir item header crosses item boundary, have %zu boundary %u", cur + sizeof(*di), item_size); return -EUCLEAN; } -- 2.17.1
