DriftfluxFoam does not produce a settling alpha field

Since the code update to 4.x, DriftfluxFoam does not settle. Now, this has been solved in OpenFOAM 4.x. I made a bugreport there: http://bugs.openfoam.org/view.php?id=2317 and it was solved by commit OpenFOAM-4.x commit 8e01ae0462c90f06af7fba33dca9fef5cb63f26e

Is it possible to merge this solution to the future release of OpenFOAM1612+?
