Minchan Kim 27d7043ecf CHROMIUM: mm: make perproc-recalim THP aware ... I got a report there is THP user with perproc reclaim. Thus, this patch adds THP page handling logic. It's almost same with MADV_FREE in that "let's do not split the THP page unless we are not sure because THP collapsing is never cheap". To achieve it, it splits the page only if we know there is only user for the page via page_mapcount check.
