    This wouldn't be the first time this week I've read this part of
    page_launder wrong, but I don't see a difference between a NULL writepage
    func, and a writepage func that returns 1. I read the code like this:

    if(PageDirty(page)) {
    if (!writepage)
    goto page_active ;
    result = writepage(page)
    if (result != 1)
    continue ;
    goto page_active ;
