The thing with the dependencies is that sometimes they are true,
sometimes they are not. What I suggested to the drbd team is that they
always just base off Linus and then ask me to pull their changes, then I
will resolve any potential conflicts when that happens. The consequence
would be that you stop pulling the drbd tree separately.
