Ceph » rbd

I was going to do this before but now I've posted the patches
for review, so I'm doing it after the fact. They're now
in need of review.

As I've been working on getting the ceph kernel messenger to
support multiple chunks of data in a single message I have
run across small changes that either are tiny bug fixes,
code cleanups, or minor refactorizations, none of which
seems worth the "paperwork" of a separate issue.

As I find these I fix them in a separate patch and move
it to the front of my patch list. And like now, I will
periodically take a group of them and put them out for
a review together.

So that's what this is about. Below is the description
I sent out ahead of the patches.

This series contains a bunch of small cleanups. All of
them I've created while working on other things, and most
of them were done in order to allow upcoming work to be
easier, or easier to understand. I've moved them all to
the front of my stack of patches and now I'm posting them
as a set for review. They apply on top of the ceph-client
"testing" branch as of a couple of days ago:
