The newly added check_block_group_item() function causes a build warning on 32-bit architectures:
fs/btrfs/tree-checker.c: In function 'check_block_group_item': fs/btrfs/tree-checker.c:404:41: error: format '%lu' expects argument of type 'long unsigned int', but argument 6 has type 'unsigned int' [-Werror=format=]
The type of a sizeof() expression is size_t, which is correctly printed using the %zu format string.
