It would be important that Johannes's patches go along with then because I'm relied on Johannes' fixes to deal with pages being inappropriately written back from reclaim context when I was analysing the workload. I'm thinking specifically about these patches mm-vmscan-scan-dirty-pages-even-in-laptop-mode.patch mm-vmscan-kick-flushers-when-we-encounter-dirty-pages-on-the-lru.patch mm-vmscan-kick-flushers-when-we-encounter-dirty-pages-on-the-lru-fix.patch mm-vmscan-remove-old-flusher-wakeup-from-direct-reclaim-path.patch mm-vmscan-only-write-dirty-pages-that-the-scanner-has-seen-twice.patch mm-vmscan-move-dirty-pages-out-of-the-way-until-theyre-flushed.patch mm-vmscan-move-dirty-pages-out-of-the-way-until-theyre-flushed-fix.patch This is 4.11 material for sure but I would not automatically try merging them to 4.10 unless those patches were also included, ideally with a rerun of just those patches against 4.10 to make sure there are no surprises lurking in there. -- Mel Gorman SUSE Labs -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
