I have considered to add the branch into gfp_to_alloc_flags() before, but didn't do it because I see that get_page_from_freelist() may use the GFP_IO or GFP_FS flag at least in zone_reclaim() path. So could you make sure it is safe to move the branch into __alloc_pages_slowpath()? If so, I will add the check into gfp_to_alloc_flags().
