I picked up your patch into master and stable-2.7, but
did the following modif on top:
commit c7d89a6dc97f72013851ae94478a4c92e77e1f56
Author: Mathieu Desnoyers <mathieu.desnoyers@efficios.com>
Date: Fri Aug 21 09:28:44 2015 -0700
Cleanup: split bdi_dirty_ratelimit with ifdef into separate macros
Makes the code easier to maintain in the long run.

Thanks!
