I would like this to go in, after your comments to the previously RFC, I guess
this has moved beyond the RFC tag. I will re-send the series without the RFC

be exercised in the same build apart from getting SMART and error injection
tests.

This shows what work still needs to be done. As of now there is SMART and error
injection which I am working on right now.

So far there is are no regressions caught.
