They are, although I did not make it clear in the cover letter, my bad. This is a CMA centric alternative to the other series that tried to issue the memcg charge through dmem[1]. CMA seemed to better fit under memcg directly as I couldn't find a solution on how to correctly charge memcg once in dmem where it was determined to double-charge or not.
