I was complaining that switching from a folio to a page interface
is a retro-step. But try_grab_page and try_grab_folio actually
both take a strut page argument and do similar but different things.
Yikes!
-int __must_check try_grab_page(struct page *page, unsigned int flags)
+int __must_check try_grab_page(struct page *page, int refs, unsigned int flags)
This would now make it a try_grab_pages. Also please try to avoid
the overly lone lines here and in the external declaration.
Ok, thanks.
