Yes, I understand that. I'm looking into a common way to validate this.
The md raid doesn't have this problem because they always call
bio_split_to_limits() first, but that's not an optimal thing to do for
dm raid in the normal read/write path, so perhaps a common checker needs
to happen generically in the block layer. Yeah, I know I removed the
previous higher level validation ... I'll try find something less costly
than what we had before.
