For brief explanations but nothing particular I can only refer you to
the commit messages. Because there have been plenty of them. :)
They're all still backward compatible as far as the userspace ABI for
older tapdisk2s goes. My recommendation would be replacing that whole
blktap/ directory, because I can't support you with more than that.
If you choose to do so: You might need some patches fixing request queue
accesses, there might be slight differences to 2.6.32, that's a bit of a
moving target sometimes. But it's not a big deal.
