The pages did not get cleaned or reclaimed by\nzone_reclaim() because the zone_reclaim_mode was unsuitable, but the lists\nare uselessly scanned frequencly making the CPU spin at near 100%.\n\nThis patchset intends to address that bug and bring the behaviour of\nzone_reclaim() more in line with expectations which were noticed during\ninvestigation. It is based on top of mmotm and takes advantage of\nKosaki\u0027s work with respect to zone_reclaim().\n\nPatch 1 fixes the heuristics that zone_reclaim() uses to determine if the\n\tscan should go ahead. The broken heuristic is what was causing the\n\tmalloc() stall as it uselessly scanned the LRU constantly. Currently,\n\tzone_reclaim is assuming zone_reclaim_mode is 1 and historically it\n\tcould not deal with tmpfs pages at all. This fixes up the heuristic so\n\tthat an unnecessary scan is more likely to be correctly avoided.\n\nPatch 2 notes that zone_reclaim() returning a failure automatically means\n\tthe zone is marked full. This is not always true. It could have\n\tfailed because the GFP mask or zone_reclaim_mode were unsuitable.\n\nPatch 3 introduces a counter zreclaim_failed that will increment each\n\ttime the zone_reclaim scan-avoidance heuristics fail. If that\n\tcounter is rapidly increasing, then zone_reclaim_mode should be\n\tset to 0 as a temporarily resolution and a bug reported because\n\tthe scan-avoidance heuristic is still broken.\n\nThis patch:\n\nOn NUMA machines, the administrator can configure zone_reclaim_mode that\nis a more targetted form of direct reclaim. On machines with large NUMA\ndistances for example, a zone_reclaim_mode defaults to 1 meaning that\nclean unmapped pages will be reclaimed if the zone watermarks are not\nbeing met.\n\nThere is a heuristic that determines if the scan is worthwhile but the\nproblem is that the heuristic is not being properly applied and is\nbasically assuming zone_reclaim_mode is 1 if it is enabled. The lack of\nproper detection can manfiest as high CPU usage as the LRU list is scanned\nuselessly.\n\nHistorically, once enabled it was depending on NR_FILE_PAGES which may\ninclude swapcache pages that the reclaim_mode cannot deal with. Patch\nvmscan-change-the-number-of-the-unmapped-files-in-zone-reclaim.patch by\nKosaki Motohiro noted that zone_page_state(zone, NR_FILE_PAGES) included\npages that were not file-backed such as swapcache and made a calculation\nbased on the inactive, active and mapped files. This is far superior when\nzone_reclaim\u003d\u003d1 but if RECLAIM_SWAP is set, then NR_FILE_PAGES is a\nreasonable starting figure.\n\nThis patch alters how zone_reclaim() works out how many pages it might be\nable to reclaim given the current reclaim_mode. If RECLAIM_SWAP is set in\nthe reclaim_mode it will either consider NR_FILE_PAGES as potential\ncandidates or else use NR_{IN}ACTIVE}_PAGES-NR_FILE_MAPPED to discount\nswapcache and other non-file-backed pages. If RECLAIM_WRITE is not set,\nthen NR_FILE_DIRTY number of pages are not candidates. If RECLAIM_SWAP is\nnot set, then NR_FILE_MAPPED are not.\n\n[kosaki.motohiro@jp.fujitsu.com: Estimate unmapped pages minus tmpfs pages]\n[fengguang.wu@intel.com: Fix underflow problem in Kosaki\u0027s estimate]\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nReviewed-by: Rik van Riel \u003criel@redhat.com\u003e\nAcked-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Wu Fengguang \u003cfengguang.wu@intel.com\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "84a892456046921a40646114deed65e2df93a1bc", "tree": "2639b6031e55988b8780960c023618c381d61c55", "parents": [ "81236810226f71bd9ff77321c8e8276dae7efc61" ], "author": { "name": "Wu Fengguang", "email": "fengguang.wu@intel.com", "time": "Tue Jun 16 15:33:17 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jun 16 19:47:45 2009 -0700" }, "message": "writeback: skip new or to-be-freed inodes\n\n1) I_FREEING tests should be coupled with I_CLEAR\n\nThe two I_FREEING tests are racy because clear_inode() can set i_state to\nI_CLEAR between the clear of I_SYNC and the test of I_FREEING.\n\n2) skip I_WILL_FREE inodes in generic_sync_sb_inodes() to avoid possible\n races with generic_forget_inode()\n\ngeneric_forget_inode() sets I_WILL_FREE call writeback on its own, so\ngeneric_sync_sb_inodes() shall not try to step in and create possible races:\n\n generic_forget_inode\n inode-\u003ei_state |\u003d I_WILL_FREE;\n spin_unlock(\u0026inode_lock);\n generic_sync_sb_inodes()\n spin_lock(\u0026inode_lock);\n __iget(inode);\n __writeback_single_inode\n // see non zero i_count\n may WARN here \u003d\u003d\u003e WARN_ON(inode-\u003ei_state \u0026 I_WILL_FREE);\n spin_unlock(\u0026inode_lock);\n may call generic_forget_inode again \u003d\u003d\u003e iput(inode);\n\nThe above race and warning didn\u0027t turn up because writeback_inodes() holds\nthe s_umount lock, so generic_forget_inode() finds MS_ACTIVE and returns\nearly.

When the use-once files crowd into the\nfile LRU, the list\u0027s \"quality\" is significantly lowered. Therefore the scan\nbalance policy in get_scan_ratio() will choose to scan the (low quality) file\nLRU much more frequently than the anon LRU.\n\nfile pages\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n\nRik proposed to *not* scan the active file LRU when the inactive list grows\nlarger than active list. This guarantees that when there are use-once streaming\nIO, and the working set is not too large(so that active_size \u003c inactive_size),\nthe active file LRU will *not* be scanned at all. So the not-too-large working\nset can be well protected.\n\nBut there are also situations where the file working set is a bit large so that\n(active_size \u003e\u003d inactive_size), or the streaming IOs are not purely use-once.\nIn these cases, the active list will be scanned slowly. Because the current\nshrink_active_list() policy is to deactivate active pages regardless of their\nreferenced bits. The deactivated pages become susceptible to the streaming IO\nattack: the inactive list could be scanned fast (500MB / 50MBps \u003d 10s) so that\nthe deactivated pages don\u0027t have enough time to get re-referenced. Because a\nuser tend to switch between windows in intervals from seconds to minutes.\n\nThis patch holds mapped executable pages in the active list as long as they\nare referenced during each full scan of the active list. Because the active\nlist is normally scanned much slower, they get longer grace time (eg. 100s)\nfor further references, which better matches the pace of user operations.\n\nTherefore this patch greatly prolongs the in-cache time of executable code,\nwhen there are moderate memory pressures.\n\n\tbefore patch: guaranteed to be cached if reference intervals \u003c I\n\tafter patch: guaranteed to be cached if reference intervals \u003c I+A\n\t\t (except when randomly reclaimed by the lumpy reclaim)\nwhere\n\tA \u003d time to fully scan the active file LRU\n\tI \u003d time to fully scan the inactive file LRU\n\nNote that normally A \u003e\u003e I.\n\nside effects\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n\nThis patch is safe in general, it restores the pre-2.6.28 mmap() behavior\nbut in a much smaller and well targeted scope.\n\nOne may worry about some one to abuse the PROT_EXEC heuristic. But as\nAndrew Morton stated, there are other tricks to getting that sort of boost.\n\nAnother concern is the PROT_EXEC mapped pages growing large in rare cases,\nand therefore hurting reclaim efficiency. But a sane application targeted for\nlarge audience will never use PROT_EXEC for data mappings. If some home made\napplication tries to abuse that bit, it shall be aware of the consequences.\nIf it is abused to scale of 2/3 total memory, it gains nothing but

The patch has almost no impact in\n this aspect, that means it won\u0027t unnecessarily increase memory pressure.\n (In contrast, your 20% mmap protection ratio will keep them all, and\n therefore eliminate the extra 41 major faults to restore working set\n of zsh etc.)\n\nThe iotrace.rb read throughput is\n\t151.194384MB/s 284.198252s 100001x 450560b --load pattern-hot-10 --play /b/sparse\nwhich means the inactive list is rotated at the speed of 250MB/s,\nso a full scan of which takes about 3.5 seconds, while a full scan\nof active file list takes about 77 seconds.\n\n2.4) X mode results\n\nWe can reach roughly the same conclusions for X desktop:\n\n nr_mapped nr_active_file nr_inactive_file pgmajfault pgdeactivate pgfree\n\n2.6.30-rc4-mm VM_EXEC protection ON:\nbegin: 9740 8920 64075 561 0 678360\nend: 768 218254 220029 565 798953 21057006\nrestore: 857 218543 220987 606 799462 21075710\nrestore X: 2414 218560 225344 797 799462 21080795\n\n2.6.30-rc4-mm VM_EXEC protection OFF:\nbegin: 9368 5035 26389 554 0 633391\nend: 770 218449 221230 661 646472 17832500\nrestore: 1113 218466 220978 710 649881 17905235\nrestore X: 2687 218650 225484 947 802700 21083584\n\n- the absolute nr_mapped drops considerably (to 1/13 of the original size)\n during the streaming IO.\n- the delta of pgmajfault is 3 vs 107 during IO, or 236 vs 393\n during the whole process.\n\nCc: Elladan \u003celladan@eskimo.com\u003e\nCc: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nAcked-by: Rik van Riel \u003criel@redhat.com\u003e\nAcked-by: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nAcked-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nReviewed-by: Johannes Weiner \u003channes@cmpxchg.org\u003e\nReviewed-by: Minchan Kim \u003cminchan.kim@gmail.com\u003e\nSigned-off-by: Wu Fengguang \u003cfengguang.wu@intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "6fe6b7e35785e3232ffe7f81d3893f1316710a02", "tree": "6f47c03735504d8aab8f7b048465b87cc5b15861", "parents": [ "608e8e66a154cbc3d591a59dcebfd9cbc9e3431a" ], "author": { "name": "Wu Fengguang", "email": "fengguang.wu@intel.com", "time": "Tue Jun 16 15:33:05 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jun 16 19:47:44 2009 -0700" }, "message": "vmscan: report vm_flags in page_referenced()\n\nCollect vma-\u003evm_flags of the VMAs that actually referenced the page.\n\nThis is preparing for more informed reclaim heuristics, eg. to protect\nexecutable file pages more aggressively.
