What I'm missing from those 0/n mails is why we need this? What is
the problem you're trying to solve and why is Peter's userspace-only
solution not enough.
Now I have a fairly good idea why we might/could/would need the kernel
interface but I don't believe the every reader has followed the whole
discussion.
So please start with the Why. Try to sell it to me as best as you can.
Details will be discussed later anyway.
Thanks.
