Although the op-version numbering is aligned with the release versions
but that doesn't go as a strict rule. If any new volume tunable option
is introduced between the release then the op-version is bumped up.
Between 3.7.7 and 3.7.9 releases there were no new options introduced
and hence the op-version goes as 30707 for 3.7.9 release.

I do think that we should add a mandatory section about the op-version
number in every release note. I'll initiate a mail about that to let all
the release maintainers/managers know about it.

Thanks,
