If we wouldn't account the gup refcounts on the tail pages during gup, we won't know anymore which tail page is pinned by gup and which is not while we run split_huge_page. But we still have to add the gup pin to the head page too, to know when we can free the compound page in case it's never -splitted during its lifetime. That requires changing not just +split during its lifetime. That requires changing not just get_page, but put_page as well so that when put_page runs on a tail page (and only on a tail page) it will find its respective head page, and then it will decrease the head page refcount in addition to the |
