Did I miss something? Can you please check the patch? The original cover letter which didn't make it to the mailing list has mentioned that. I have reposted it now. Anyway this is on top of http://marc.info/?l=linux-kernel&m=141779091114777 which hasn't landed into -mm tree at the time I was posting this.
