Currently we do not tell mm to zero out tail of the page before truncate in orphan_cleanup(). This is ok, because the page should not be uptodate, however this may eventually change and I might cause problems. Call truncate_inode_pages() as precautionary measure. Thanks Jan Kara for pointing this out.
