'o2cb' refers to the stuff in ocfs2_nodemanager, so we wanted to keep it out
of the fs namespace (think more "cluster" than "file system").

We felt at the time (and still do) that it was better than polluting
/sys/fs/ with non file system related things.

Also, I feel that for perspective, I should mention that this layout isn't
anything new - we've been doing this for a while.

Changing a path (or just testing two of them) isn't a big deal, the problem
is that existing versions of ocfs2-tools will break very badly. That's
clearly unnaceptable for a production file system.
