| A D | transhuge.rst | 115 - get_page()/put_page() and GUP operate on head page's ->_refcount.
117 - ->_refcount in tail pages is always zero: get_page_unless_zero() never
155 split_huge_page uses migration entries to stabilize page->_refcount and
161 All tail pages have zero ->_refcount until atomic_add(). This prevents the
