    Subject[PATCH 2/5] ext4: ext4_rename should dirty dir_bh with the correct directory
    When ext4_rename performs a directory rename (move), dir_bh is a buffer that is
    modified to update the '..' link in the directory being moved (old_inode).
    However, ext4_handle_dirty_metadata is called with the old parent directory
    inode (old_dir) and dir_bh, which is incorrect because dir_bh does not belong
    to the parent inode. Fix this error.
