Subject[PATCH 02/16] ext4: ext4_rename should dirty dir_bh with the correct directory
From
Date
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.
