I thought checkpatch didn't want to see spaces after a '*', so
"struct foo * ptr" should become "struct foo *ptr".

I also think that "struct page **page" should be renamed to "struct page
**ppage" or "struct page **pages", to avoid confusion with many other
functions which pass a "struct page *" pointer to a variable named "page".
