This obviously has to be:
diff --git a/drivers/md/raid1.c b/drivers/md/raid1.c
index ff89839455ec..3570da63969b 100644

                if (!bio_add_page(behind_bio, page, len, 0)) {
-                       free_page(page);

                        goto free_pages;
                }
 

But I wonder why I dint see it in my allmodconfig build. 

Jens can you fold that in or do you want me to update the patch?
