The patch titled Subject: mm: enable CONFIG_COMPACTION by default has been removed from the -mm tree. Its filename was mm-enable-config_compaction-by-default.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Rik van Riel <riel@xxxxxxxxxx> Subject: mm: enable CONFIG_COMPACTION by default Now that lumpy reclaim has been removed, compaction is the only way left to free up contiguous memory areas.
