I don't think "compress" is the right terminology here. It is more
like "share" a page.
Why not support raid6 here?


Thanks a lot for your reviewing and suggestion.
Since it need to modify more existing code to support raid6, this series
have not do it. I will try to support raid6 in next version.

Thanks,
Yufen
