From b12c4ad14ee0232ad47c2bef404b6d42a3578332 Mon Sep 17 00:00:00 2001 From: Minchan Kim Date: Mon, 8 Oct 2012 16:32:08 -0700 Subject: mm: page_alloc: use get_freepage_migratetype() instead of page_private() The page allocator uses set_page_private and page_private for handling migratetype when it frees page. Let's replace them with [set|get] _freepage_migratetype to make it more clear.
