Hi Kirill, I've noticed that your commit 83929372f629 (filemap: prepare find and delete operations for huge pages) added to page_cache_tree_delete(): int i, nr = PageHuge(page) ? 1 : hpage_nr_pages(page); Isn't the logic computing 'nr' inverted? I'd expect that if page is !PageHuge, we want to delete just one page... OTOH I'm surprised this would not blow up anywhere if it was really wrong so maybe I just miss something.
