The patch titled Hugepages: Use page_to_nid rather than traversing zone pointers has been removed from the -mm tree. Its filename is hugepages-use-page_to_nid-rather-than-traversing-zone-pointers.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ Subject: Hugepages: Use page_to_nid rather than traversing zone pointers From: Christoph Lameter <clameter@xxxxxxx> I found two location in hugetlb.c where we chase pointer instead of using page_to_nid(). Page_to_nid is more effective and can get the node directly from page flags.
