3.16.83-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Wang Shilong <wangsl.fnst@xxxxxxxxxxxxxx>
commit c01a5c074c0f6f85a3b02e39432b9e5576ab51de upstream.
inline data is stored from offset of @disk_bytenr in
struct btrfs_file_extent_item. So substracting total
size of struct btrfs_file_extent_item is wrong, fix it.
