+ ---help---
+ A RAID-6 set of N drives with a capacity of C MB per drive
+ provides the capacity of C * (N - 2) MB, and protects
+ against a failure of any two drives. For a given sector
+ (row) number, (N - 2) drives contain data sectors, and two
+ drives contains two independent redundancy syndromes. Like
+ RAID-5, RAID-6 distributes the syndromes across the drives
+ in one of the available parity distribution methods.
+
+ RAID-6 requires mdadm-1.5.0 or later, available at:
+
+ ftp://ftp.kernel.org/pub/linux/utils/raid/mdadm/
+
+ If you want to use such a RAID-6 set, say Y. To compile
+ this code as a module, choose M here: the module will be
+ called raid6.
+
+ If unsure, say Y.
