Ceph » rbd

There are bits and pieces of the new request code
documented for the kernel rbd client--in the comments
and in the commit logs. But I'd like to put together
an informal design document that describes how it all
work.

And I guess I'd like to do it soon, while it's all
fairly fresh. (I can also be sure things that
reviewers find difficult or confusing are covered.)

I expect I'd store the result under the Linux Documentation
subdirectory.
