RAID-6 works! (At least it seems to...)
Well, at least I have a piece of code that passes my relatively simple functionality tests. Still, that's news, and this is the first RAID-6 snapshot that isn't *known* to be broken :)
I can at least mount filesystems, read and write data, reboot the system and have the data still there, with 1 or 2 disks lost, and do a reconstruction once the drives are added back in.
New development snapshot at:
ftp://ftp.kernel.org/pub/linux/kernel/people/hpa/raid6-20031224-experimental.tar.gz
Please test it out and let me know how badly it sucks :)
At some point I'll try to run some benchmarks. There is also a lot of optimization still to be done.

[And again, thanks to Penguin Computing for donating a test system, without which this would never have happened.]
