Acked-by: John Stultz <john.stultz@xxxxxxxxxx> On a slightly related note, I'm starting to regret the current heap-helpers approach (Andrew probably gets an "I told you so" there :). While it avoids a lot of duplication, it's really an all or nothing approach, and doesn't really compare well to other drm style helper functions. I may eventually try to break the system and cma implementations out of the helper code and try to consider a different approach to avoid the duplication. thanks -john
