Its filename was mm-compaction-cleanup-isolate_freepages-fix-2.patch This patch was dropped because it was folded into mm-compaction-cleanup-isolate_freepages.patch ------------------------------------------------------ From: Vlastimil Babka <vbabka@xxxxxxx> Subject: mm-compaction-cleanup-isolate_freepages-fix 2 Cleanup detection of compaction scanners crossing in isolate_freepages(). To make sure compact_finished() observes scanners crossing, we can just set free_pfn to migrate_pfn instead of confusing max() construct.
