Subject[PATCH next 1/2] btrfs: tree-checker: Fix error format string
Date
From: Andreas Färber <afaerber@suse.com>

Argument BTRFS_FILE_EXTENT_INLINE_DATA_START is defined as offsetof(),
which returns type size_t, so we need %zu instead of %lu.

This fixes a build warning on 32-bit arm:

../fs/btrfs/tree-checker.c: In function 'check_extent_data_item':
../fs/btrfs/tree-checker.c:230:43: warning: format '%lu' expects argument of type 'long unsigned int', but argument 5 has type 'unsigned int' [-Wformat=]
230 | "invalid item size, have %u expect [%lu, %u)",
| ~~^
| |
| long unsigned int
| %u

Fixes: a31ccb4b7ba2 ("btrfs: tree-checker: Check item size before reading file extent type")
