Yes, I can try. I'll give it a little more thought on Monday.

But I have an initial question: why do you need this patch?
Specifically, is there a driver you have that supports/needs this
change? Right now, your new flag won't be used for anything new.

Side note: I have always thought that it was strange to have
subpage-read support only baked into SOFT_ECC mode. There are
presumably many potential applications in which a non-SOFT_ECC system
could read partial pages safely.
