On kmemleak_init(), the entry is found in the\nearly_log[] but not the object_tree_root, and this error message is\ndisplayed.\n\nIf alloc_page() fails then it defaults back to vmalloc() which still uses\nthe kmemleak_alloc() which makes us still need the kmemleak_not_leak()\ncall.

This will guarantee that get_page_unless_zero() can never\nsucceed on any tail page. page_tail-\u003e_mapcount is guaranteed zero and\nis unused for all tail pages of a compound page, so we can simply\naccount the tail page references there and transfer them to\ntail_page-\u003e_count in __split_huge_page_refcount() (in addition to the\nhead_page-\u003e_mapcount).\n\nWhile debugging this s/_count/_mapcount/ change I also noticed get_page is\ncalled by direct-io.c on pages returned by get_user_pages. That wasn\u0027t\nentirely safe because the two atomic_inc in get_page weren\u0027t atomic. As\nopposed to other get_user_page users like secondary-MMU page fault to\nestablish the shadow pagetables would never call any superflous get_page\nafter get_user_page returns. It\u0027s safer to make get_page universally safe\nfor tail pages and to use get_page_foll() within follow_page (inside\nget_user_pages()). get_page_foll() is safe to do the refcounting for tail\npages without taking any locks because it is run within PT lock protected\ncritical sections (PT lock for pte and page_table_lock for\npmd_trans_huge).\n\nThe standard get_page() as invoked by direct-io instead will now take\nthe compound_lock but still only for tail pages. The direct-io paths\nare usually I/O bound and the compound_lock is per THP so very\nfinegrined, so there\u0027s no risk of scalability issues with it. A simple\ndirect-io benchmarks with all lockdep prove locking and spinlock\ndebugging infrastructure enabled shows identical performance and no\noverhead. So it\u0027s worth it. Ideally direct-io should stop calling\nget_page() on pages returned by get_user_pages(). The spinlock in\nget_page() is already optimized away for no-THP builds but doing\nget_page() on tail pages returned by GUP is generally a rare operation\nand usually only run in I/O paths.\n\nThis new refcounting on page_tail-\u003e_mapcount in addition to avoiding new\nRCU critical sections will also allow the working set estimation code to\nwork without any further complexity associated to the tail page\nrefcounting with THP.\n\nSigned-off-by: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nReported-by: Michel Lespinasse \u003cwalken@google.com\u003e\nReviewed-by: Michel Lespinasse
