That's clearly necessary, also to bring OCFS2 more uptodate with the
latest happenings in the GFS2 world; it'll allow both file systems to
share exactly the same cluster stack.

There's one question I have; how will this handle

- the "old" user-space code starting on a new kernel,
- or the "new" user-space code being run on an old kernel?

Is there anything we can do to at least provide a meaningful error
message in the first case? The second should be easier to handle.
