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 ;
