OK. But we'll need to coordinate a bit so that the first patch (the
one that introduces the template) is available in both branches,
otherwise ESSIV will be broken in the dm branch until it hits another
branch (-next or mainline) that also contains cryptodev.

As I suggested before, I can easily create a branch based on v5.3-rc1
containing just the first ESSIV patch (once Herbert is happy with it),
and merge that both into cryptodev and dm. That way, both will
continue to work without having too much overlap. Since adding a
template/file that has no users yet is highly unlikely to break
anything, it doesn't even matter which branch gets pulled first.

Any idea about the status of the EBOIV patch?
