For more context: on Android, we've historically scanned each processes's address space using /proc/pid/smaps (and /proc/pid/smaps_rollup more recently) to extract memory management statistics. We're looking at replacing this mechanism with the new /proc/pid/status per-memory-type (e.g., anonymous, file-backed) counters so that we can be even more efficient, but we'd like the counts we collect to be accurate.
If you need the accuracy then why don't you simply make SPLIT_RSS_COUNTING configurable and disable it in your setup? -- Michal Hocko SUSE Labs -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
