It\ndoes not play well with cgroups or the better NUMA placement code in\ndevelopment, since we have only one swap token globally.\n\nIt also has the potential to mess with scalability of the system, by\nincreasing the number of non-reclaimable pages on the active and\ninactive anon LRU lists.\n\nLast but not least, the swap token code has been broken for a year\nwithout complaints, as reported by Konstantin Khlebnikov. This suggests\nwe no longer have much use for it.\n\nThe days of sub-1G memory systems with heavy use of swap are over. If\nwe ever need thrashing reducing code in the future, we will have to\nimplement something that does scale.\n\nChange-Id: I6d287cfc3c3206ca24da2de0c1392e5fdfcfabe8\nSigned-off-by: Rik van Riel \u003criel@redhat.com\u003e\nCc: Konstantin Khlebnikov \u003ckhlebnikov@openvz.org\u003e\nAcked-by: Johannes Weiner \u003channes@cmpxchg.org\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Hugh Dickins \u003chughd@google.com\u003e\nAcked-by: Bob Picco \u003cbpicco@meloft.net\u003e\nAcked-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nGit-commit: e709ffd6169ccd259eb5874e853303e91e94e829\nGit-repo: git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git\nSigned-off-by: Laura Abbott \u003clauraa@codeaurora.org\u003e\n" }, { "commit": "d4c9b4298f72e8778fb3ae1013e9e421f7cc64a6", "tree": "0ab047c985d50174b841eae8c27c59131a07b6b7", "parents": [ "fa16809ac46e0229da33ce6e5863288c9c3f700e" ], "author": { "name": "Konstantin Khlebnikov", "email": "khlebnikov@openvz.org", "time": "Tue May 29 15:06:54 2012 -0700" }, "committer": { "name": "Ethan Chen", "email": "intervigil@gmail.com", "time": "Fri Jan 17 22:12:14 2014 -0800" }, "message": "mm/memcg: kill mem_cgroup_lru_del()\n\nThis patch kills mem_cgroup_lru_del(), we can use\nmem_cgroup_lru_del_list() instead.

I expected this would happen for kswapd and impair\nallocation success rates (https://lkml.org/lkml/2012/1/25/166) but I did\nnot anticipate this much a difference: 80% less scanning, 37% less\nreclaim by kswapd\n\nIn comparison, reclaim/compaction is not aggressive and gives up easily\nwhich is the intended behaviour. hugetlbfs uses __GFP_REPEAT and would\nbe much more aggressive about reclaim/compaction than THP allocations\nare. The stress test above is allocating like neither THP or hugetlbfs\nbut is much closer to THP.\n\nMainline is now impaired in terms of high order allocation under heavy\nload although I do not know to what degree as I did not test with\n__GFP_REPEAT. Keep this in mind for bugs related to hugepage pool\nresizing, THP allocation and high order atomic allocation failures from\nnetwork devices.\n\nIn terms of congestion throttling, I see the following for this test\n\n FTrace Reclaim Statistics: congestion_wait\n Direct number congest waited 3 0 0 0\n Direct time congest waited 0ms 0ms 0ms 0ms\n Direct full congest waited 0 0 0 0\n Direct number conditional waited 957 512 1081 1075\n Direct time conditional waited 0ms 0ms 0ms 0ms\n Direct full conditional waited 0 0 0 0\n KSwapd number congest waited 36 4 3 5\n KSwapd time congest waited 3148ms 400ms 300ms 500ms\n KSwapd full congest waited 30 4 3 5\n KSwapd number conditional waited 88514 197 332 542\n KSwapd time conditional waited 4980ms 0ms 0ms 0ms\n KSwapd full conditional waited 49 0 0 0\n\nThe \"conditional waited\" times are the most interesting as this is\ndirectly impacted by the number of dirty pages encountered during scan.\nAs lumpy reclaim is no longer scanning contiguous ranges, it is finding\nfewer dirty pages. This brings wait times from about 5 seconds to 0.\nkswapd itself is still calling congestion_wait() so it\u0027ll still stall but\nit\u0027s a lot less.\n\nIn terms of the type of IO we were doing, I see this\n\n FTrace Reclaim Statistics: mm_vmscan_writepage\n Direct writes anon sync 0 0 0 0\n Direct writes anon async 0 0 0 0\n Direct writes file sync 0 0 0 0\n Direct writes file async 0 0 0 0\n Direct writes mixed sync 0 0 0 0\n Direct writes mixed async 0 0 0 0\n KSwapd writes anon sync 0 0 0 0\n KSwapd writes anon async 91682 0 0 0\n KSwapd writes file sync 0 0 0 0\n KSwapd writes file async 822629 0 0 0\n KSwapd writes mixed sync 0 0 0 0\n KSwapd writes mixed async 0 0 0 0\n\nIn 3.2, kswapd was doing a bunch of async writes of pages but\nreclaim/compaction was never reaching a point where it was doing sync\nIO. This does not guarantee that reclaim/compaction was not calling\nwait_on_page_writeback() but I would consider it unlikely. It indicates\nthat merging patches 2 and 3 to stop reclaim/compaction calling\nwait_on_page_writeback() should be safe.\n\nThis patch:\n\nLumpy reclaim had a purpose but in the mind of some, it was to kick the\nsystem so hard it trashed. For others the purpose was to complicate\nvmscan.c. Over time it was giving softer shoes and a nicer attitude but\nmemory compaction needs to step up and replace it so this patch sends\nlumpy reclaim to the farm.\n\nThe tracepoint format changes for isolating LRU pages with this patch\napplied. Furthermore reclaim/compaction can no longer queue dirty pages\nin pageout() if the underlying BDI is congested. Lumpy reclaim used\nthis logic and reclaim/compaction was using it in error.\n\nChange-Id: Ib2992962c9e99cf250a7f859bb2a67034051e4d4\nSigned-off-by: Mel Gorman \u003cmgorman@suse.de\u003e\nAcked-by: Rik van Riel \u003criel@redhat.com\u003e\nAcked-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Konstantin Khlebnikov \u003ckhlebnikov@openvz.org\u003e\nCc: Hugh Dickins \u003chughd@google.com\u003e\nCc: Ying Han \u003cyinghan@google.com\u003e\nCc: Andy Whitcroft \u003capw@shadowen.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nGit-commit: c53919adc045bf803252e912f23028a68525753d\nGit-repo: git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git\nSigned-off-by: Laura Abbott \u003clauraa@codeaurora.org\u003e\n" }, { "commit": "67bed6808090539cefdc0ecd2738e12ba8bc037e", "tree": "554f4cf1f7d9ec8997ffbbf74d0a5284f98cd17c", "parents": [ "1bee7b9b43a3b5530c62523d582aef7c3f7028ca" ], "author": { "name": "Arun Bharadwaj", "email": "abharadw@codeaurora.org", "time": "Wed Jul 03 10:35:02 2013 -0700" }, "committer": { "name": "Ethan Chen", "email": "intervigil@gmail.com", "time": "Fri Jan 17 22:12:13 2014 -0800" }, "message": "tracing/sched: Add trace events to track cpu hotplug.\n\nAdd ftrace event trace_sched_cpu_hotplug to track cpu\nhot-add and hot-remove events.\n\nThis is useful in a variety of power, performance and\ndebug analysis scenarios.\n\nChange-Id: I5d202c7a229ffacc3aafb7cf9afee0b0ee7b0931\nSigned-off-by: Arun Bharadwaj \u003cabharadw@codeaurora.org\u003e\n" }, { "commit": "1bee7b9b43a3b5530c62523d582aef7c3f7028ca", "tree": "65467bc85c4f505afd64c09d4044c1645c1ecc56", "parents": [ "3bb998ff6cbde07fdd25d039487195c29b17def1" ], "author": { "name": "Syed Rameez Mustafa", "email": "rameezmustafa@codeaurora.org", "time": "Mon Jul 15 11:52:09 2013 -0700" }, "committer": { "name": "Ethan Chen", "email": "intervigil@gmail.com", "time": "Fri Jan 17 22:12:13 2014 -0800" }, "message": "kernel/lib: add additional debug capabilites for data corruption\n\nData corruptions in the kernel often end up in system crashes that\nare easier to debug closer to the time of detection.

It also more naturally reflects the logic by the callers of\nverify_iovec.\n\nWith this change in place I could remove \"\nif (!uaddr || msg_sys-\u003emsg_namelen \u003d\u003d 0)\n\tmsg-\u003emsg_name \u003d NULL\n\".\n\nThis change does not alter the user visible error logic as we ignore\nmsg_namelen as long as msg_name is NULL.\n\nAlso remove two unnecessary curly brackets in ___sys_recvmsg and change\ncomments to netdev style.\n\nCc: David Miller \u003cdavem@davemloft.net\u003e\nSuggested-by: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nSigned-off-by: Hannes Frederic Sowa \u003channes@stressinduktion.org\u003e\nSigned-off-by: David S.

This problem happened on v3.4, but it seems issue still lives\nin current tree, the reason is do_try_to_free_pages enter live lock:\n\nkswapd will go to sleep if the zones have been fully scanned and are still\nnot balanced. As kswapd thinks there\u0027s little point trying all over again\nto avoid infinite loop. Instead it changes order from high-order to\n0-order because kswapd think order-0 is the most important. Look at\n73ce02e9 in detail. If watermarks are ok, kswapd will go back to sleep\nand may leave zone-\u003eall_unreclaimable \u003d3D 0. It assume high-order users\ncan still perform direct reclaim if they wish.\n\nDirect reclaim continue to reclaim for a high order which is not a\nCOSTLY_ORDER without oom-killer until kswapd turn on\nzone-\u003eall_unreclaimble\u003d . This is because to avoid too early oom-kill.\nSo it means direct_reclaim depends on kswapd to break this loop.\n\nIn worst case, direct-reclaim may continue to page reclaim forever when\nkswapd sleeps forever until someone like watchdog detect and finally kill\nthe process. As described in:\nhttp://thread.gmane.org/gmane.linux.kernel.mm/103737\n\nWe can\u0027t turn on zone-\u003eall_unreclaimable from direct reclaim path because\ndirect reclaim path don\u0027t take any lock and this way is racy. Thus this\npatch removes zone-\u003eall_unreclaimable field completely and recalculates\nzone reclaimable state every time.\n\nNote: we can\u0027t take the idea that direct-reclaim see zone-\u003epages_scanned\ndirectly and kswapd continue to use zone-\u003eall_unreclaimable. Because, it\nis racy. commit 929bea7c71 (vmscan: all_unreclaimable() use\nzone-\u003eall_unreclaimable as a name) describes the detail.\n\nCRs-fixed: 573027\nChange-Id: I49970a0fa751cf33af293fd1ee784e36422785b1\n[akpm@linux-foundation.org: uninline zone_reclaimable_pages() and zone_reclaimable()]\nCc: Aaditya Kumar \u003caaditya.kumar.30@gmail.com\u003e\nCc: Ying Han \u003cyinghan@google.com\u003e\nCc: Nick Piggin \u003cnpiggin@gmail.com\u003e\nAcked-by: Rik van Riel \u003criel@redhat.com\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Christoph Lameter \u003ccl@linux.com\u003e\nCc: Bob Liu \u003clliubbo@gmail.com\u003e\nCc: Neil Zhang \u003czhangwm@marvell.com\u003e\nCc: Russell King - ARM Linux \u003clinux@arm.linux.org.uk\u003e\nReviewed-by: Michal Hocko \u003cmhocko@suse.cz\u003e\nAcked-by: Minchan Kim \u003cminchan@kernel.org\u003e\nAcked-by: Johannes Weiner \u003channes@cmpxchg.org\u003e\nSigned-off-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nSigned-off-by: Lisa Du \u003ccldu@marvell.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nGit-repo: git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git\nGit-commit: 6e543d5780e36ff5ee56c44d7e2e30db3457a7ed\n[lauraa@codeaurora.org: Some context fixups and variable name changes due\nto backporting.

The main contention comes\nfrom swap_info_get(). This patch tries to fix the gap with adding a new\nper-partition lock.\n\nGlobal data like nr_swapfiles, total_swap_pages, least_priority and\nswap_list are still protected by swap_lock.\n\nnr_swap_pages is an atomic now, it can be changed without swap_lock. In\ntheory, it\u0027s possible get_swap_page() finds no swap pages but actually\nthere are free swap pages. But sounds not a big problem.\n\nAccessing partition specific data (like scan_swap_map and so on) is only\nprotected by swap_info_struct.lock.\n\nChanging swap_info_struct.flags need hold swap_lock and\nswap_info_struct.lock, because scan_scan_map() will check it. read the\nflags is ok with either the locks hold.\n\nIf both swap_lock and swap_info_struct.lock must be hold, we always hold\nthe former first to avoid deadlock.\n\nswap_entry_free() can change swap_list. To delete that code, we add a\nnew highest_priority_index. Whenever get_swap_page() is called, we\ncheck it.

And\nBTW, looks get_swap_page() doesn\u0027t really need the lock. We never free\nswap_info[] and we check SWAP_WRITEOK flag. The only risk without the\nlock is we could swapout to some low priority swap, but we can quickly\nrecover after several rounds of swap, so sounds not a big deal to me.\nBut I\u0027d prefer to fix this if it\u0027s a real problem.\n\n\"swap: make each swap partition have one address_space\" improved the\nswapout speed from 1.7G/s to 2G/s.

In this case the bug\nsurfaced when the Fibre Channel port connection for a well-known address\nwas closed during a concurrent adapter shut-down procedure, which is a\nrare constellation.\n\nThis patch also fixes these warnings from the sparse tool (make C\u003d1):\n\ndrivers/s390/scsi/zfcp_qdio.c:224:12: warning: context imbalance in\n \u0027zfcp_qdio_sbal_check\u0027 - wrong count at exit\ndrivers/s390/scsi/zfcp_qdio.c:244:5: warning: context imbalance in\n \u0027zfcp_qdio_sbal_get\u0027 - unexpected unlock\n\nLast but not least, we get rid of that crappy lock-unlock-lock\nsequence at the beginning of the critical section.\n\nIt is okay to call zfcp_erp_adapter_reopen() with req_q_lock held.\n\nReported-by: Mikulas Patocka \u003cmpatocka@redhat.com\u003e\nReported-by: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\nSigned-off-by: Martin Peschke \u003cmpeschke@linux.vnet.ibm.com\u003e\nSigned-off-by: Steffen Maier \u003cmaier@linux.vnet.ibm.com\u003e\nSigned-off-by: James Bottomley \u003cJBottomley@Parallels.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n\n" }, { "commit": "09a818b021b0f6cadf602b85ff8c5e5ceada8b47", "tree": "37206885f07695d207dee0f174fbc72d74941ba5", "parents": [ "51cc7b551add9c0be5982539f236f9145cd7f141", "747b79875b3e85084869c6b51d35387f10419bbe" ], "author": { "name": "Ethan Chen", "email": "intervigil@gmail.com", "time": "Wed Aug 28 16:40:27 2013 -0700" }, "committer": { "name": "Ethan Chen", "email": "intervigil@gmail.com", "time": "Wed Aug 28 16:40:27 2013 -0700" }, "message": "Merge tag \u0027AU_LINUX_ANDROID_JB_2.6.04.03.00.109.025\u0027 into cm-10.2\n\nAU_LINUX_ANDROID_JB_2.6.04.03.00.109.025 based on quic/aosp/jb_2.6\n\nConflicts:\n\tdrivers/media/video/msm/msm_mctl.c\n\tdrivers/media/video/msm/msm_v4l2_video.c\n\nChange-Id: Ib467ade6f770034967d1904ac11beace0053cea7\n" }, { "commit": "1d821b2eda8c8d7fc09f6c150b82247602f6939d", "tree": "2389aa5ed298908d63790de28d4dcbe70d9bf5b8", "parents": [ "4b298b691b067fea09161af8476f21da21b6abc4" ], "author": { "name": "Subhash Jadavani", "email": "subhashj@codeaurora.org", "time": "Tue Jun 25 13:13:24 2013 +0530" }, "committer": { "name": "Gerrit - the friendly Code Review server", "email": "code-review@localhost", "time": "Thu Aug 22 23:11:59 2013 -0700" }, "message": "mmc: core: expose HPI capability to SWITCH commands\n\nSome of the time consuming operations such as BKOPS, SANITIZE, CACHE\nflush/off use the SWITCH command (CMD6) but as these operations don\u0027t\nhave card specification defined timeout for completion, we may see\ntimeout errors if card doesn\u0027t complete the operation within the SW\ndefined timeout.

This should result in an unique identifier for each futex.\n\nThough this is not true when futexes are located in different subpages\nof an hugepage. The reason is, that the mapping index for all those\nfutexes evaluates to the index of the base page of the hugetlbfs\nmapping. So a futex at offset 0 of the hugepage mapping and another\none at offset PAGE_SIZE of the same hugepage mapping have identical\nfutex_keys. This happens because the futex code blindly uses\npage-\u003eindex.\n\nSteps to reproduce the bug:\n\n1. Map a file from hugetlbfs. Initialize pthread_mutex1 at offset 0\n and pthread_mutex2 at offset PAGE_SIZE of the hugetlbfs\n mapping.\n\n The mutexes must be initialized as PTHREAD_PROCESS_SHARED because\n PTHREAD_PROCESS_PRIVATE mutexes are not affected by this issue as\n their keys solely depend on the user space address.\n\n2. Lock mutex1 and mutex2\n\n3. Create thread1 and in the thread function lock mutex1, which\n results in thread1 blocking on the locked mutex1.\n\n4. Create thread2 and in the thread function lock mutex2, which\n results in thread2 blocking on the locked mutex2.\n\n5. Unlock mutex2. Despite the fact that mutex2 got unlocked, thread2\n still blocks on mutex2 because the futex_key points to mutex1.\n\nTo solve this issue we need to take the normal page index of the page\nwhich contains the futex into account, if the futex is in an hugetlbfs\nmapping. In other words, we calculate the normal page mapping index of\nthe subpage in the hugetlbfs mapping.\n\nMappings which are not based on hugetlbfs are not affected and still\nuse page-\u003eindex.\n\nThanks to Mel Gorman who provided a patch for adding proper evaluation\nfunctions to the hugetlbfs code to avoid exposing hugetlbfs specific\ndetails to the futex code.\n\n[ tglx: Massaged changelog ]\n\nSigned-off-by: Zhang Yi \u003czhang.yi20@zte.com.cn\u003e\nReviewed-by: Jiang Biao \u003cjiang.biao2@zte.com.cn\u003e\nTested-by: Ma Chenggong \u003cma.chenggong@zte.com.cn\u003e\nReviewed-by: \u0027Mel Gorman\u0027 \u003cmgorman@suse.de\u003e\nAcked-by: \u0027Darren Hart\u0027 \u003cdvhart@linux.intel.com\u003e\nCc: \u0027Peter Zijlstra\u0027 \u003cpeterz@infradead.org\u003e\nLink: http://lkml.kernel.org/r/000101ce71a6%24a83c5880%24f8b50980%24@com\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Mike Galbraith \u003cmgalbraith@suse.de\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n\n\n" }, { "commit": "99593eb7ca1dd9bfaa431d96e009eda23f001ace", "tree": "b1412f07fda67143bc2454bbb6f81e124cae3617", "parents": [ "65280b8ed1cca78ff7fe63ecfdb0fff87fe184a3" ], "author": { "name": "Andrew Vagin", "email": "avagin@openvz.org", "time": "Fri Aug 02 21:16:43 2013 +0400" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Wed Aug 14 22:57:08 2013 -0700" }, "message": "tracing: Fix fields of struct trace_iterator that are zeroed by mistake\n\ncommit ed5467da0e369e65b247b99eb6403cb79172bcda upstream.\n\ntracing_read_pipe zeros all fields bellow \"seq\".
