He's done it on top of http://git.infradead.org/users/willy/pagecache.git I was hoping he'd include http://git.infradead.org/users/willy/pagecache.git/commitdiff/c71de787328809026cfabbcc5485cb01caca8646 http://git.infradead.org/users/willy/pagecache.git/commitdiff/f3a1cd6447e29a54b03efc2189d943f12ac1c9b9 http://git.infradead.org/users/willy/pagecache.git/commitdiff/c03d3a5a5716bb0df2fe15ec528bbd895cd18e6e as the first three patches in the series; then it should apply to Linus' tree.
