Hello, I would like to have discussion on future of transparent huge pages. I work on better refcounting for THP[1] which should help to overcome some scalability issues and make semantics around split_huge_page() simpler. It's also step toward THP in page cache: unlike my previous attempt on the topic with new refcounting we will not need new lock in io path to protect against splitting.
