The challenge here is that there isn't an active ocfs2 tree at the
moment (git/jlbec/ocfs2.git was last updated 11 years ago), and it's
not clear ocfs2 has an active maintainer, although as discussed at a
recent ext4 telechat, there still are some enterprise users of it
hanging on.

We're starting considering changes to fs/jbd2 so we can get off of
using the struct bh for jbd2 (still very early days; it's more in the
early concept brain-storming stage.) And since ocfs2 also uses
fs/jbd2, the fact that ocfs2 isn't under active maintenance is going
to be more of a challenge moving forward.

Something we should discuss in the hallway track of LSF/MM, perhaps...
