hbukittbd: Andrew Morton proposes new userspace/kernelspace interface.

Rusty Russel is an author of the vringfd() (name says it all) new interface for the event ring buffer management.
Quotation from Andrew Morton:

This is may be our third high-bandwidth user/kernel interface to transport bulk data ("hbukittbd") which was implemented because its predecessors weren't quite right. In a year or two's time someone else will need a hbukittbd and will find that the existing three aren't quite right and will give us another one. One day we need to stop doing this ;)
...
So I think it would be good to plonk the proposed interface on the table and have a poke at it. Is it compat-safe? Is it extensible in a backward-compatible fashion? Are there future-safe changes we should make to it? Can Michael Kerrisk understand, review and document it? etc.

You know what I'm saying ;) What is the proposed interface?
