The patch titled Subject: mm, vmscan: make shrink_node decisions more node-centric -fix has been removed from the -mm tree. Its filename was mm-vmscan-make-shrink_node-decisions-more-node-centric-fix.patch This patch was dropped because it was folded into mm-vmscan-make-shrink_node-decisions-more-node-centric.patch ------------------------------------------------------ From: Mel Gorman <mgorman@xxxxxxxxxxxxxxxxxxx> Subject: mm, vmscan: make shrink_node decisions more node-centric -fix The patch "mm, vmscan: make shrink_node decisions more node-centric" checks whether compaction is suitable on empty nodes. This is expensive rather than wrong but is worth fixing. This is a fix to the mmotm patch mm-vmscan-make-shrink_node-decisions-more-node-centric.patch Link: http://lkml.kernel.org/r/1468588165-12461-2-git-send-email-mgorman@xxxxxxxxxxxxxxxxxxx Signed-off-by: Mel Gorman <mgorman@xxxxxxxxxxxxxxxxxxx> Acked-by: Minchan Kim <minchan@xxxxxxxxxx> Acked-by: Johannes Weiner <hannes@xxxxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- mm/vmscan.c | 2 ++ 1 file changed, 2 insertions(+) diff -puN mm/vmscan.c~mm-vmscan-make-shrink_node-decisions-more-node-centric-fix mm/vmscan.c --- a/mm/vmscan.c~mm-vmscan-make-shrink_node-decisions-more-node-centric-fix +++ a/mm/vmscan.c @@ -2414,6 +2414,8 @@ static inline bool should_continue_recla /* If compaction would go ahead or the allocation would succeed, stop */ for (z = 0; z <= sc->reclaim_idx; z++) { struct zone *zone = &pgdat->node_zones[z]; + if (!populated_zone(zone)) + continue; switch (compaction_suitable(zone, sc->order, 0, sc->reclaim_idx)) { case COMPACT_PARTIAL: _ Patches currently in -mm which might be from mgorman@xxxxxxxxxxxxxxxxxxx are mm-meminit-remove-early_page_nid_uninitialised.patch mm-vmstat-add-infrastructure-for-per-node-vmstats.patch mm-vmscan-move-lru_lock-to-the-node.patch mm-vmscan-move-lru-lists-to-node.patch mm-mmzone-clarify-the-usage-of-zone-padding.patch mm-vmscan-begin-reclaiming-pages-on-a-per-node-basis.patch mm-vmscan-have-kswapd-only-scan-based-on-the-highest-requested-zone.patch mm-vmscan-make-kswapd-reclaim-in-terms-of-nodes.patch mm-vmscan-remove-balance-gap.patch mm-vmscan-simplify-the-logic-deciding-whether-kswapd-sleeps.patch mm-vmscan-by-default-have-direct-reclaim-only-shrink-once-per-node.patch mm-vmscan-remove-duplicate-logic-clearing-node-congestion-and-dirty-state.patch mm-vmscan-do-not-reclaim-from-kswapd-if-there-is-any-eligible-zone.patch mm-vmscan-make-shrink_node-decisions-more-node-centric.patch mm-memcg-move-memcg-limit-enforcement-from-zones-to-nodes.patch mm-workingset-make-working-set-detection-node-aware.patch mm-page_alloc-consider-dirtyable-memory-in-terms-of-nodes.patch mm-move-page-mapped-accounting-to-the-node.patch mm-rename-nr_anon_pages-to-nr_anon_mapped.patch mm-move-most-file-based-accounting-to-the-node.patch mm-move-most-file-based-accounting-to-the-node-fix.patch mm-move-vmscan-writes-and-file-write-accounting-to-the-node.patch mm-vmscan-only-wakeup-kswapd-once-per-node-for-the-requested-classzone.patch mm-page_alloc-wake-kswapd-based-on-the-highest-eligible-zone.patch mm-convert-zone_reclaim-to-node_reclaim.patch mm-vmscan-avoid-passing-in-classzone_idx-unnecessarily-to-shrink_node.patch mm-vmscan-avoid-passing-in-classzone_idx-unnecessarily-to-compaction_ready.patch mm-vmscan-avoid-passing-in-classzone_idx-unnecessarily-to-compaction_ready-fix.patch mm-vmscan-avoid-passing-in-remaining-unnecessarily-to-prepare_kswapd_sleep.patch mm-vmscan-have-kswapd-reclaim-from-all-zones-if-reclaiming-and-buffer_heads_over_limit.patch mm-vmscan-have-kswapd-reclaim-from-all-zones-if-reclaiming-and-buffer_heads_over_limit-fix.patch mm-vmscan-add-classzone-information-to-tracepoints.patch mm-page_alloc-remove-fair-zone-allocation-policy.patch mm-page_alloc-cache-the-last-node-whose-dirty-limit-is-reached.patch mm-vmstat-replace-__count_zone_vm_events-with-a-zone-id-equivalent.patch mm-vmstat-account-per-zone-stalls-and-pages-skipped-during-reclaim.patch mm-vmstat-account-per-zone-stalls-and-pages-skipped-during-reclaim-fix.patch mm-vmstat-print-node-based-stats-in-zoneinfo-file.patch mm-vmstat-remove-zone-and-node-double-accounting-by-approximating-retries.patch mm-vmstat-remove-zone-and-node-double-accounting-by-approximating-retries-fix.patch mm-pagevec-release-reacquire-lru_lock-on-pgdat-change.patch mm-vmscan-update-all-zone-lru-sizes-before-updating-memcg.patch mm-vmscan-remove-redundant-check-in-shrink_zones.patch mm-vmscan-release-reacquire-lru_lock-on-pgdat-change.patch mm-vmscan-release-reacquire-lru_lock-on-pgdat-change-fix.patch mm-add-per-zone-lru-list-stat-fix.patch mm-vmscan-remove-highmem_file_pages.patch mm-vmscan-remove-highmem_file_pages-fix.patch mm-remove-reclaim-and-compaction-retry-approximations.patch mm-consider-whether-to-decivate-based-on-eligible-zones-inactive-ratio.patch mm-vmscan-account-for-skipped-pages-as-a-partial-scan.patch -- To unsubscribe from this list: send the line "unsubscribe mm-commits" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
