  "message": "hugetlb: move refcounting in hugepage allocation inside hugetlb_lock\n\nCurrently alloc_huge_page() raises page refcount outside hugetlb_lock.\nbut it causes race when dequeue_hwpoison_huge_page() runs concurrently\nwith alloc_huge_page().\nTo avoid it, this patch moves set_page_refcounted() in hugetlb_lock.\n\nSigned-off-by: Naoya Horiguchi \u003cn-horiguchi@ah.jp.nec.com\u003e\nSigned-off-by: Wu Fengguang \u003cfengguang.wu@intel.com\u003e\nAcked-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nReviewed-by: Christoph Lameter \u003ccl@linux.com\u003e\nSigned-off-by: Andi Kleen \u003cak@linux.intel.com\u003e\n",
