I think we could make a case for getting Sameer's patch at http://marc.info/?l=linux-kernel&m=138436313021133 to be merged for stable, but then we'd have to revert it in linux-next before merging your series at http://marc.info/?l=linux-kernel&m=138616217925981. All of the issues you present in that series seem to be stable material, so why not just go ahead with your series and mark it for stable for 3.13? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
