  "message": "mm: numa: Migrate pages handled during a pmd_numa hinting fault\n\nTo say that the PMD handling code was incorrectly transferred from autonuma\nis an understatement. The intention was to handle a PMDs worth of pages\nin the same fault and effectively batch the taking of the PTL and page\nmigration. The copied version instead has the impact of clearing a number\nof pte_numa PTE entries and whether any page migration takes place depends\non racing. This just happens to work in some cases.\n\nThis patch handles pte_numa faults in batch when a pmd_numa fault is\nhandled. The pages are migrated if they are currently misplaced.\nEssentially this is making an assumption that NUMA locality is\non a PMD boundary but that could be addressed by only setting\npmd_numa if all the pages within that PMD are on the same node\nif necessary.\n\nSigned-off-by: Mel Gorman \u003cmgorman@suse.de\u003e\n",
