	[ce5d36aa] ore: Support for raid 6 (2014-05-22 14:48:15 +0300)

proud to present support for raid6 in ORE.
These simple patches will enable raid6 using the Kernel's raid6_pq engine
for support under exofs and pnfs-objects. There is nothing needed to do
at exofs and pnfs-obj. Just fire your mkfs.exofs with --raid=6 (that was
already supported before) and off you go as usual. The ORE will pick up
the new map and will start writing two devices of redundancy bits.
The patches are so simple because most of the ORE was already for the
general raid case, only a few bug fixes were needed and the actual wiring
into the raid6_pq engine.

Thanks
Boaz
