I am confronted with a big problem of the raid6 algorithm, when recently I learn the raid6 code of linux 2.6 you have contributed . Unfortunately I can not understand the algorithm of P +Q parity in this program . Is this some formula for this raid6 algorithm? I realy respect your help,could you show me some details about this algorithm? - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
