So not knowing the soft tlb refill code of ppc64 in great\ndetail I\u0027m not removing the \"speculative\" page_count increase and the\npte checks across all the code, but unless there\u0027s a strong reason for\nit they should be later cleaned up too.\n\nIf a pte can change from huge to non-huge (like it could happen with\nTHP) passing a pte_t *ptep to gup_hugepte() would also require to repeat\nthe is_hugepd in gup_hugepte(), but that shouldn\u0027t happen with hugetlbfs\nonly so I\u0027m not altering that.\n\nSigned-off-by: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Hugh Dickins \u003chughd@google.com\u003e\nCc: Johannes Weiner \u003cjweiner@redhat.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Mel Gorman \u003cmgorman@suse.de\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nAcked-by: David Gibson \u003cdavid@gibson.dropbear.id.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "2839bdc1bfc0af76a2f0f11eca011590520a04fa", "tree": "8dddcc4c964e50cb5067bfd23f3fb660400dbc2b", "parents": [ "70b50f94f1644e2aa7cb374819cfd93f3c28d725" ], "author": { "name": "Andrea Arcangeli", "email": "aarcange@redhat.com", "time": "Wed Nov 02 13:37:03 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Nov 02 16:06:57 2011 -0700" }, "message": "powerpc: remove superfluous PageTail checks on the pte gup_fast\n\nThis part of gup_fast doesn\u0027t seem capable of handling hugetlbfs ptes,\nthose should be handled by gup_hugepd only, so these checks are\nsuperfluous.\n\nPlus if this wasn\u0027t a noop, it would have oopsed because, the insistence\nof using the speculative refcounting would trigger a VM_BUG_ON if a tail\npage was encountered in the page_cache_get_speculative().\n\nSigned-off-by: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Hugh Dickins \u003chughd@google.com\u003e\nCc: Johannes Weiner \u003cjweiner@redhat.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Mel Gorman \u003cmgorman@suse.de\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nAcked-by: David Gibson \u003cdavid@gibson.dropbear.id.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "70b50f94f1644e2aa7cb374819cfd93f3c28d725", "tree": "79198cd9a92600140827a670d1ed5eefdcd23d79", "parents": [ "994c0e992522c123298b4a91b72f5e67ba2d1123" ], "author": { "name": "Andrea Arcangeli", "email": "aarcange@redhat.com", "time": "Wed Nov 02 13:36:59 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Nov 02 16:06:57 2011 -0700" }, "message": "mm: thp: tail page refcounting fix\n\nMichel while working on the working set estimation code, noticed that\ncalling get_page_unless_zero() on a random pfn_to_page(random_pfn)\nwasn\u0027t safe, if the pfn ended up being a tail page of a transparent\nhugepage under splitting by __split_huge_page_refcount().\n\nHe then found the problem could also theoretically materialize with\npage_cache_get_speculative() during the speculative radix tree lookups\nthat uses get_page_unless_zero() in SMP if the radix tree page is freed\nand reallocated and get_user_pages is called on it before\npage_cache_get_speculative has a chance to call get_page_unless_zero().\n\nSo the best way to fix the problem is to keep page_tail-\u003e_count zero at\nall times. 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
