Subject: mm-add-replace_page_cache_page-function-add-freepage-hook
From: Minchan Kim <minchan.kim@xxxxxxxxx>
6072d13c ("Call the filesystem back whenever a page is removed from the
page cache") added new freepage hook in page cache drop function.
So, replace_page_cache_page should call freepage to support page cleanup
to fs.
