    md/raid5: finish support for DDF/raid6 · 67cc2b81
    NeilBrown authored
    DDF requires RAID6 calculations over different devices in a different
    order.
    For md/raid6, we calculate over just the data devices, starting
    immediately after the 'Q' block.
    For ddf/raid6 we calculate over all devices, using zeros in place of
    the P and Q blocks.
    
    This requires unfortunately complex loops...
