I was waiting for them to settle down before paying more attention. My general take is that these patches address a single workload on exceedingly rare and expensive machines. If they adversely affect common and cheap machines via code complexity, memory footprint or via runtime impact then it would be pretty hard to justify their inclusion. Do we have measurements of the negative and/or positive impact on smaller machines? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
