  "message": "mm: numa: Sanitize task_numa_fault() callsites\n\nThere are three callers of task_numa_fault():\n\n - do_huge_pmd_numa_page():\n     Accounts against the current node, not the node where the\n     page resides, unless we migrated, in which case it accounts\n     against the node we migrated to.\n\n - do_numa_page():\n     Accounts against the current node, not the node where the\n     page resides, unless we migrated, in which case it accounts\n     against the node we migrated to.\n\n - do_pmd_numa_page():\n     Accounts not at all when the page isn\u0027t migrated, otherwise\n     accounts against the node we migrated towards.\n\nThis seems wrong to me; all three sites should have the same\nsementaics, furthermore we should accounts against where the page\nreally is, we already know where the task is.\n\nSo modify all three sites to always account; we did after all receive\nthe fault; and always account to where the page is after migration,\nregardless of success.\n\nThey all still differ on when they clear the PTE/PMD; ideally that\nwould get sorted too.\n\nSigned-off-by: Mel Gorman \u003cmgorman@suse.de\u003e\nReviewed-by: Rik van Riel \u003criel@redhat.com\u003e\nCc: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nCc: Johannes Weiner \u003channes@cmpxchg.org\u003e\nCc: Srikar Dronamraju \u003csrikar@linux.vnet.ibm.com\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nLink: http://lkml.kernel.org/r/1381141781-10992-8-git-send-email-mgorman@suse.de\nSigned-off-by: Ingo Molnar \u003cmingo@kernel.org\u003e\n",
