Robert Buchholz f2e29ad691 Repair mode for raid6 
In repair mode, raid6check will rewrite one single stripe
by regenerating the data (or parity) of two raid devices that
are specified via the command line.
If you need to rewrite just one slot, pick any other slot
at random.

Note that the repair option will change data on the disks
directly, so both the md layer above as well as any layers
above md (such as filesystems) may be accessing the stripe
data from cached buffers. Either instruct the kernels
to drop the caches or reassemble the raid after repair.
