There's existing userspace dependencies on numa_maps already, though, so owell. I had to fix numa_maps output when autonuma was merged for a much more subtle difference at http://marc.info/?l=git-commits-head&m=139113691614467 so I know some people actually parse this and care quite a bit about its accuracy, it's a shame it can't be deprecated in favor of adding the necessary information to smaps. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
