The version number place holder in the mainline is not useful.
Because a mainline kernel ships with only one ocfs2 module,
we don't need the version# in the module. Hence we've stopped
updating it. Maybe we should just remove it. But that does not
mean it does not have the features. If you are looking for the list
of features in the mainline, then just look at mkfs.ocfs2's manpage.
It lists the mainline kernel version the feature was added in.

The ocfs2 module version was only required because we were
shipping ocfs2 outside of the kernel (for RHEL). OCFS2 1.4 is the
last release under that model.

Going forward, ocfs2 will only be available with the kernel. (I mean
there is nothing stopping a person from distributing it however
they want. But that's highly unlikely.)

OL, SLES, Fedora, Debian, OpenSUSE, ubuntu.... all ship ocfs2 along
with the kernel. If it is not in your distro, ping the vendor.
