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=]
