Lines Matching refs:tail

260 head or tail pages as usual (exactly as they would do on
264 if any driver is going to mangle over the page structure of the tail
266 for the head page and not the tail page), it should be updated to jump
268 split_huge_page() to avoid the head and tail pages to disappear from
362 page to the tail pages before clearing all PG_head/tail bits from the
365 and tail pages if running get_user_pages on an address backed by any
366 hugepage), requires the refcount to be accounted on the tail pages and
368 split_huge_page while there are gup pins established on any tail
370 on any tail page, would mean having to split all hugepages upfront in
375 accounting the pins on the tail pages for hugetlbfs). If we wouldn't
376 account the gup refcounts on the tail pages during gup, we won't know
377 anymore which tail page is pinned by gup and which is not while we run
381 get_page, but put_page as well so that when put_page runs on a tail
382 page (and only on a tail page) it will find its respective head page,
384 tail page refcount. To obtain a head page reliably and to decrease its
