OK, I agree I thought of that too. My bakethon post had a narrower scope
to just the "adding multiple segment handling" & "last-byte handling"
(I think let me check)

But I thought for simplicity since this patchset was reviewed then, I've
tested with this patch and it works good as well. If you are going to
break things up, I can test with the minimal patches and report what is
need in Stable. (Is anyone working on it?)

Thanks
