First an apology, I thought it was in your tree, but it looks like
the drbd branch just has minor fixes.  So a lot less urgency.

Do you have a pointer to that discussion?  I can't remember one.

I don't think that's a a usual pattern.  Also the new version looks
like a complete rewrite and not something incremental:

 45 files changed, 45891 insertions(+), 16264 deletions(-)

For a code base that is "29482 total".

I think reviewing it would be easier by just adding an new drbd9 driver
and then steering people toward it carefully, as that is actually
reviewable compared to non-bisectable patches changing large chunks
of code in a non-atomic way.
