Very nice work. Thanks for doing this!

I think it's a much needed cleanup. I focused mainly on the core block,
discard, write same and sd.c pieces and everything looks sensible to me.

I wonder what the best approach is to move a patch set with this many
stakeholders forward? Set a "speak now or forever hold your peace"
review deadline?
