Is anyone else working on parity support for the ccd driver?

RAID-4 style parity, with a dedicated parity disk, seems like it might not
be too tough.  Striped parity, probably somewhat harder.

I am very busy.  If nobody else is working on this, I might well do at least
support for a dedicated parity disk.  If someone else is working on this,
I'll probably just wait.  So let me know, OK? :-)
