need to inject hwpoison to a collection of\nselected task pages, and must not touch pages not owned by them and\nthus kill important system processes such as init. (But it\u0027s OK to\nmis-hwpoison free/unowned pages as well as shared clean pages.\nMis-hwpoison of shared dirty pages will kill all tasks, so the test\nsuite will target all or non of such tasks in the first place.)\n\nThe memory cgroup serves this purpose well. We can put the target\nprocesses under the control of a memory cgroup, and tell the hwpoison\ninjection code to only kill pages associated with some active memory\ncgroup.\n\nThe prerequisite for doing hwpoison stress tests with mem_cgroup is,\nthe mem_cgroup code tracks task pages _accurately_ (unless page is\nlocked). Which we believe is/should be true.\n\nThe benefits are simplification of hwpoison injector code. Also the\nmem_cgroup code will automatically be tested by hwpoison test cases.\n\nThe alternative interfaces pin-pfn/unpin-pfn can also delegate the\n(process and page flags) filtering functions reliably to user space.\nHowever prototype implementation shows that this scheme adds more\ncomplexity than we wanted.\n\nExample test case:\n\n\tmkdir /cgroup/hwpoison\n\n\tusemem -m 100 -s 1000 \u0026\n\techo `jobs -p` \u003e /cgroup/hwpoison/tasks\n\n\tmemcg_ino\u003d$(ls -id /cgroup/hwpoison | cut -f1 -d\u0027 \u0027)\n\techo $memcg_ino \u003e /debug/hwpoison/corrupt-filter-memcg\n\n\tpage-types -p `pidof init` --hwpoison # shall do nothing\n\tpage-types -p `pidof usemem` --hwpoison # poison its pages\n\n[AK: Fix documentation]\n[Add fix for problem noticed by Li Zefan \u003clizf@cn.fujitsu.com\u003e;\ndentry in the css could be NULL]\n\nCC: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCC: Hugh Dickins \u003chugh.dickins@tiscali.co.uk\u003e\nCC: Daisuke Nishimura \u003cnishimura@mxp.nes.nec.co.jp\u003e\nCC: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\nCC: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCC: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nCC: Paul Menage \u003cmenage@google.com\u003e\nCC: Nick Piggin \u003cnpiggin@suse.de\u003e\nCC: Andi Kleen \u003candi@firstfloor.org\u003e\nSigned-off-by: Wu Fengguang \u003cfengguang.wu@intel.com\u003e\nSigned-off-by: Andi Kleen \u003cak@linux.intel.com\u003e\n" }, { "commit": "478c5ffc0b50527bd2390f2daa46cc16276b8413", "tree": "f58f5be9760fd0e81567611cf6e9f9bc77d1d3cd", "parents": [ "1a9b5b7fe0c5dad8a635288882d36785dea742f9" ], "author": { "name": "Wu Fengguang", "email": "fengguang.wu@intel.com", "time": "Wed Dec 16 12:19:59 2009 +0100" }, "committer": { "name": "Andi Kleen", "email": "ak@linux.intel.com", "time": "Wed Dec 16 12:19:59 2009 +0100" }, "message": "HWPOISON: add page flags filter\n\nWhen specified, only poison pages if ((page_flags \u0026 mask) \u003d\u003d value).\n\n- corrupt-filter-flags-mask\n- corrupt-filter-flags-value\n\nThis allows stress testing of many kinds of pages.\n\nStrictly speaking, the buddy pages requires taking zone lock, to avoid\nsetting PG_hwpoison on a \"was buddy but now allocated to someone\" page.\nHowever we can just do nothing because we set PG_locked in the beginning,\nthis prevents the page allocator from allocating it to someone.

SLAB_POISON, and\nSLAB_STORE_USER.\n\nConsequently, it may require that the minimum possible slab order needed\nto allocate a single object be greater when using these options. The\nmost notable example is for objects that are PAGE_SIZE bytes in size.\n\nHigher minimum slab orders may cause page allocation failures when oom or\nunder heavy fragmentation.\n\nThis patch adds a new slub_debug option, which disables debugging by\ndefault for caches that would have resulted in higher minimum orders:\n\n\tslub_debug\u003dO\n\nWhen this option is used on systems with 4K pages, kmalloc-4096, for\nexample, will not have debugging enabled by default even if\nCONFIG_SLUB_DEBUG_ON is defined because it would have resulted in a\norder-1 minimum slab order.\n\nReported-by: Larry Finger \u003cLarry.Finger@lwfinger.net\u003e\nTested-by: Larry Finger \u003cLarry.Finger@lwfinger.net\u003e\nCc: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nSigned-off-by: David Rientjes \u003crientjes@google.com\u003e\nSigned-off-by: Pekka Enberg \u003cpenberg@cs.helsinki.fi\u003e\n" }, { "commit": "0bd8df908de2aefe312d05bd25cd3abc21a6d1da", "tree": "4d12cb3b723789175015646da3c1c8bada0e2a2a", "parents": [ "3b47883d93e941cb2b2df9ab46b2bdb66116c992" ], "author": { "name": "Andrew Morton", "email": "akpm@linux-foundation.org", "time": "Tue Jun 16 22:38:29 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Jun 17 09:45:46 2009 -0700" }, "message": "Documentation/vm/Makefile: don\u0027t try to build slqbinfo\n\nFor it is only in linux-next at this stage.\n\nCc: Wu Fengguang \u003cfengguang.wu@intel.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Matt Mackall \u003cmpm@selenic.com\u003e\nCc: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Pekka Enberg \u003cpenberg@cs.helsinki.fi\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "35efa5e993a7a00a50b87d2b7725c3eafc80b083", "tree": "d46d3840f274c2c933498ab0225e8341d7695e72", "parents": [ "17e895012f7fe9dc63144990da98c41bbc22d68f" ], "author": { "name": "Wu Fengguang", "email": "fengguang.wu@intel.com", "time": "Tue Jun 16 15:32:27 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jun 16 19:47:38 2009 -0700" }, "message": "pagemap: add page-types tool\n\nAdd page-types, a handy tool for querying page flags.\n\nIt will expand some of the overloaded flags:\n\tPG_slob_free \u003d PG_private\n\tPG_slub_frozen \u003d PG_active\n\tPG_slub_debug \u003d PG_error\n\tPG_readahead \u003d PG_reclaim\n\nand mask out obscure flags except in -raw mode:\n\tPG_reserved\n\tPG_mlocked\n\tPG_mappedtodisk\n\tPG_private\n\tPG_private_2\n\tPG_owner_priv_1\n\tPG_arch_1\n\tPG_uncached\n\tPG_compound* for non hugeTLB pages\n\n[akpm@linux-foundation.org: fix warning]\nSigned-off-by: Wu Fengguang \u003cfengguang.wu@intel.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Matt Mackall \u003cmpm@selenic.com\u003e\nCc: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "17e895012f7fe9dc63144990da98c41bbc22d68f", "tree": "430c333e2d23bf2fbf057ec9a5b3685eba217d99", "parents": [ "c9ba78e226057a1c2f19671383c496df187c02b5" ], "author": { "name": "Wu Fengguang", "email": "fengguang.wu@intel.com", "time": "Tue Jun 16 15:32:26 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jun 16 19:47:38 2009 -0700" }, "message": "pagemap: document 9 more exported page flags\n\nAlso add short descriptions for all of the 20 exported page flags.\n\nSigned-off-by: Wu Fengguang \u003cfengguang.wu@intel.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Matt Mackall \u003cmpm@selenic.com\u003e\nCc: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "c9ba78e226057a1c2f19671383c496df187c02b5", "tree": "8e28df19b0304fc58bb854d812661e628b7ac612", "parents": [ "177975495914efb372f7edee28ba9a0fdb754149" ], "author": { "name": "Wu Fengguang", "email": "fengguang.wu@intel.com", "time": "Tue Jun 16 15:32:25 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jun 16 19:47:38 2009 -0700" }, "message": "pagemap: document clarifications\n\nSome bit ranges were inclusive and some not.

Suspect this is the\ncause of an observed 2-3% slowdown in page fault testing relative to kernel\nwithout this patch series.\n\nTo alleviate this, use an internal mode flag, MPOL_F_LOCAL in the mempolicy\nflags member which is guaranteed [?] to be in the same cacheline as the mode\nitself.\n\nVerified that reworked mempolicy now performs slightly better on 25-rc8-mm1\nfor both anon and shmem segments with system default and vma [preferred local]\npolicy.\n\nSigned-off-by: Lee Schermerhorn \u003clee.schermerhorn@hp.com\u003e\nCc: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "bea904d54d6faa92400f10c8ea3d3828b8e1eb93", "tree": "24966dd4dabadb4bb32aa1e00fae2c2168661229", "parents": [ "52cd3b074050dd664380b5e8cfc85d4a6ed8ad48" ], "author": { "name": "Lee Schermerhorn", "email": "lee.schermerhorn@hp.com", "time": "Mon Apr 28 02:13:18 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Apr 28 08:58:24 2008 -0700" }, "message": "mempolicy: use MPOL_PREFERRED for system-wide default policy\n\nCurrently, when one specifies MPOL_DEFAULT via a NUMA memory policy API\n[set_mempolicy(), mbind() and internal versions], the kernel simply installs a\nNULL struct mempolicy pointer in the appropriate context: task policy, vma\npolicy, or shared policy. This causes any use of that policy to \"fall back\"\nto the next most specific policy scope.\n\nThe only use of MPOL_DEFAULT to mean \"local allocation\" is in the system\ndefault policy. This requires extra checks/cases for MPOL_DEFAULT in many\nmempolicy.c functions.\n\nThere is another, \"preferred\" way to specify local allocation via the APIs.\nThat is using the MPOL_PREFERRED policy mode with an empty nodemask.\nInternally, the empty nodemask gets converted to a preferred_node id of \u0027-1\u0027.\nAll internal usage of MPOL_PREFERRED will convert the \u0027-1\u0027 to the id of the\nnode local to the cpu where the allocation occurs.\n\nSystem default policy, except during boot, is hard-coded to \"local\nallocation\". By using the MPOL_PREFERRED mode with a negative value of\npreferred node for system default policy, MPOL_DEFAULT will never occur in the\n\u0027policy\u0027 member of a struct mempolicy. Thus, we can remove all checks for\nMPOL_DEFAULT when converting policy to a node id/zonelist in the allocation\npaths.\n\nIn slab_node() return local node id when policy pointer is NULL. No need to\nset a pol value to take the switch default. Replace switch default with\nBUG()--i.e., shouldn\u0027t happen.\n\nWith this patch MPOL_DEFAULT is only used in the APIs, including internal\ncalls to do_set_mempolicy() and in the display of policy in\n/proc/\u003cpid\u003e/numa_maps. It always means \"fall back\" to the the next most\nspecific policy scope. This simplifies the description of memory policies\nquite a bit, with no visible change in behavior.\n\nget_mempolicy() continues to return MPOL_DEFAULT and an empty nodemask when\nthe requested policy [task or vma/shared] is NULL. These are the values one\nwould supply via set_mempolicy() or mbind() to achieve that condition--default\nbehavior.\n\nThis patch updates Documentation to reflect this change.\n\nSigned-off-by: Lee Schermerhorn \u003clee.schermerhorn@hp.com\u003e\nCc: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "52cd3b074050dd664380b5e8cfc85d4a6ed8ad48", "tree": "fcfcf55c0e81376ea34919fab26e29bedd7f3b88", "parents": [ "a6020ed759404372e8be2b276e85e51735472cc9" ], "author": { "name": "Lee Schermerhorn", "email": "lee.schermerhorn@hp.com", "time": "Mon Apr 28 02:13:16 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Apr 28 08:58:24 2008 -0700" }, "message": "mempolicy: rework mempolicy Reference Counting [yet again]\n\nAfter further discussion with Christoph Lameter, it has become clear that my\nearlier attempts to clean up the mempolicy reference counting were a bit of\noverkill in some areas, resulting in superflous ref/unref in what are usually\nfast paths. In other areas, further inspection reveals that I botched the\nunref for interleave policies.\n\nA separate patch, suitable for upstream/stable trees, fixes up the known\nerrors in the previous attempt to fix reference counting.\n\nThis patch reworks the memory policy referencing counting and, one hopes,\nsimplifies the code. Maybe I\u0027ll get it right this time.\n\nSee the update to the numa_memory_policy.txt document for a discussion of\nmemory policy reference counting that motivates this patch.\n\nSummary:\n\nLookup of mempolicy, based on (vma, address) need only add a reference for\nshared policy, and we need only unref the policy when finished for shared\npolicies. So, this patch backs out all of the unneeded extra reference\ncounting added by my previous attempt. It then unrefs only shared policies\nwhen we\u0027re finished with them, using the mpol_cond_put() [conditional put]\nhelper function introduced by this patch.\n\nNote that shmem_swapin() calls read_swap_cache_async() with a dummy vma\ncontaining just the policy. read_swap_cache_async() can call alloc_page_vma()\nmultiple times, so we can\u0027t let alloc_page_vma() unref the shared policy in\nthis case. To avoid this, we make a copy of any non-null shared policy and\nremove the MPOL_F_SHARED flag from the copy. This copy occurs before reading\na page [or multiple pages] from swap, so the overhead should not be an issue\nhere.\n\nI introduced a new static inline function \"mpol_cond_copy()\" to copy the\nshared policy to an on-stack policy and remove the flags that would require a\nconditional free. The current implementation of mpol_cond_copy() assumes that\nthe struct mempolicy contains no pointers to dynamically allocated structures\nthat must be duplicated or reference counted during copy.\n\nSigned-off-by: Lee Schermerhorn \u003clee.schermerhorn@hp.com\u003e\nCc: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "45c4745af381851b0406d8e4db99e62e265691c2", "tree": "d93f6f7b3d7eb3773aaa80444c56baff99e670d6", "parents": [ "ae4d8c16aa22775f5731677abb8a82f03cec877e" ], "author": { "name": "Lee Schermerhorn", "email": "lee.schermerhorn@hp.com", "time": "Mon Apr 28 02:13:12 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Apr 28 08:58:24 2008 -0700" }, "message": "mempolicy: rename struct mempolicy \u0027policy\u0027 member to \u0027mode\u0027\n\nThe terms \u0027policy\u0027 and \u0027mode\u0027 are both used in various places to describe the\nsemantics of the value stored in the \u0027policy\u0027 member of struct mempolicy.\nFurthermore, the term \u0027policy\u0027 is used to refer to that member, to the entire\nstruct mempolicy and to the more abstract concept of the tuple consisting of a\n\"mode\" and an optional node or set of nodes.

This works by specifying\n\nslub_debug\u003d-\n\nas a kernel parameter.\n\nDave Jones wanted this feature.\nhttp://marc.info/?l\u003dlinux-kernel\u0026m\u003d118072189913045\u0026w\u003d2\n\n[akpm@linux-foundation.org: clean up switch statement]\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "c1aee215d760175601b820bd1e2f0364e844ff8c", "tree": "afbbbe64b57552fa55a0ee95b01922f64ecec0a1", "parents": [ "9af20376ee65cd2d13f7eb587fab70879d8c355b" ], "author": { "name": "Christoph Lameter", "email": "clameter@sgi.com", "time": "Thu May 31 00:40:47 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu May 31 07:58:13 2007 -0700" }, "message": "SLUB: More documentation\n\nUpdate documentation to describe how to read a SLUB error report.\nAdd slub parameters to Documentation/kernel-parameters.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: \"Randy.Dunlap\" \u003crdunlap@xenotime.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "32f9306b161a5e0c892132f7227f36de94090289", "tree": "69a04fdd1d38e535af7729be18e4244dad4b1013", "parents": [ "223a10a98135da38d3668973d72cdffb1ced4b7d" ], "author": { "name": "Christoph Lameter", "email": "clameter@sgi.com", "time": "Fri May 18 00:36:43 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri May 18 08:17:17 2007 -0700" }, "message": "slub: another slabinfo fix\n\nThe slab manipulation functions should not be triggered by slabs that\nare unresovable in the subset of slabs selected on the command line.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "eefaca9c3246f3daf56e7ed02987f79abcee7087", "tree": "1eac21979f536f7a08ae77d4b59f1c615eef5b94", "parents": [ "ade3aff25fb2dce76e2a9b53e1334bd0a174f739" ], "author": { "name": "Christoph Lameter", "email": "clameter@sgi.com", "time": "Wed May 16 22:10:55 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu May 17 05:23:03 2007 -0700" }, "message": "SLUB: slabinfo fixes\n\nAlign the output of % with K/M/G of sizes.\n\nCheck for empty NUMA information to avoid segfault on !NUMA.\n\n-r should work directly not only if we match a single slab\n without additional options.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "a87615b8f9e2349f6d3770af3d72fd6a41ab4239", "tree": "5e2608dad1ad746b0552ef52afec9298320045ac", "parents": [ "be7b3fbcef34452127bed93632b8e788f685d70e" ], "author": { "name": "Christoph Lameter", "email": "clameter@sgi.com", "time": "Wed May 09 02:32:37 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed May 09 12:30:44 2007 -0700" }, "message": "SLUB: slabinfo upgrade\n\n-e Show empty slabs\n-d Modification of slab debug options at runtime\n-o Operations.
