| D | transhuge.rst | 125 - get_page()/put_page() and GUP operate in head page's ->_refcount.
127 - ->_refcount in tail pages is always zero: get_page_unless_zero() never
165 split_huge_page uses migration entries to stabilize page->_refcount and
171 All tail pages have zero ->_refcount until atomic_add(). This prevents the
173 atomic_add() we don't care about the ->_refcount value. We already known how
