It would break ocfs2-tools, majorly. mount.ocfs2, fsck.ocfs2, tunefs.ocfs2,
mkfs.ocfs2, o2cb_ctl are just the programs which I can think of off the top
of my head which look for o2cb/interface_revision. Basically anything that
needs to interact with the cluster uses that file at least once.

So sorry, but shuffling it around would make many Ocfs2 users very, very
unhappy.
