apologies for not being clear here -

if you look for 'XOR' in the code it basically shows that the degraded mode
operation portion for raid5 is just a placeholder:

            if (rdp->status & AR_S_DEGRADED) {
                /* do the XOR game if possible */
            }

and is not yet implemented

(etc)

so while it might work for normal mode - it doesn't buy you much in the
event of a drive failure
