      We need to make sure that older clients do not try to read the parity components. This can probably be handled by setting the layout pattern of the parity components to LOV_PATTERN_PARITY, but this needs to be tested. It may be desirable to exclude the LOV_PATTERN_PARITY components from the layout that is sent to older clients, since 2.15.x does not (yet) have patch https://review.whamcloud.com/51060 ("LU-16837 llite: handle unknown layout component") to handle FLR-EC layouts properly.
