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.
