ext4_writepage currently has a and else case after the
page_has_buffers() check where it does I/O if there are no buffers
attached.  But given how ext4 uses a write_begin method that always
creates buffer, the normal set_page_dirty which creates buffers
and a ->page_mkwrite that creates buffers I just can't see how that case
can happen at all.
