Miller" , linux-arch@vger.kernel.org From: Michal Hocko __GFP_REPEAT has a rather weak semantic but since it has been introduced around 2.6.12 it has been ignored for low order allocations. {pud,pmd}_alloc_one is using __GFP_REPEAT but it always allocates from pgtable_cache which is initialzed to PAGE_SIZE objects. This means that this flag has never been actually useful here because it has always been used only for PAGE_ALLOC_COSTLY requests. Cc: "David S.
