First of all, very impressive work here. Major kudos to Neil Brown for adding and maintaining such well-written and useful code to the Linux kernel.
Second, I would like to know whether the code needed for the RAID5->RAID6 and RAID6->RAID5 conversions have been backported into the current "stable" 2.6.27.x (ie. 18.104.22.168 as of this moment). Also, will mdadm >= 3.1 (which I understand is also needed for these conversions) work with this "stable" kernel?
Thanks, -- Durval Menezes
