+         This is a one-shot self test that permutes through the
+         recovery of all the possible two disk failure scenarios for a
+         N-disk array.  Recovery is performed with the asynchronous
+         raid6 recovery routines, and will optionally use an offload
+         engine if one is available.
+ 
+         If unsure, say N.
