I guess the cleanest way is to hook into dequeue_huge_page_node and add something like arch_clear_hugepage_flags.I hooked into enqueue_huge_page instead, but how about something like this?:
Do you have any specific reason for that? enqueue_huge_page is called on pages which potentially never get used so isn't that wasting a bit? Not that it would be wrong I was just thinking why shouldn't we do it when the page is actualy going to be used for sure. -- Michal Hocko SUSE Labs -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
