So add some test routines to the raid6 checker that can prove if the new xor_syndrome() works as expected. Run through all permutations of start/stop pages per algorithm and simulate a xor_syndrome() assisted rmw run. After each rmw check if the recovery algorithm still confirms that the stripe is fine.
