The nodes_allowed mask is derived as follows:\n\n* For \"default\" [NULL] task mempolicy, a NULL nodemask_t pointer\n is produced. This will cause the hugetlb subsystem to use\n node_online_map as the \"nodes_allowed\". This preserves the\n behavior before this patch.\n* For \"preferred\" mempolicy, including explicit local allocation,\n a nodemask with the single preferred node will be produced.\n \"local\" policy will NOT track any internode migrations of the\n task adjusting nr_hugepages.\n* For \"bind\" and \"interleave\" policy, the mempolicy\u0027s nodemask\n will be used.\n* Other than to inform the construction of the nodes_allowed node\n mask, the actual mempolicy mode is ignored. That is, all modes\n behave like interleave over the resulting nodes_allowed mask\n with no \"fallback\".\n\nSee the updated documentation [next patch] for more information\nabout the implications of this patch.\n\nExamples:\n\nStarting with:\n\n\tNode 0 HugePages_Total: 0\n\tNode 1 HugePages_Total: 0\n\tNode 2 HugePages_Total: 0\n\tNode 3 HugePages_Total: 0\n\nDefault behavior [with or without this patch] balances persistent\nhugepage allocation across nodes [with sufficient contiguous memory]:\n\n\tsysctl vm.nr_hugepages[_mempolicy]\u003d32\n\nyields:\n\n\tNode 0 HugePages_Total: 8\n\tNode 1 HugePages_Total: 8\n\tNode 2 HugePages_Total: 8\n\tNode 3 HugePages_Total: 8\n\nOf course, we only have nr_hugepages_mempolicy with the patch,\nbut with default mempolicy, nr_hugepages_mempolicy behaves the\nsame as nr_hugepages.\n\nApplying mempolicy--e.g., with numactl [using \u0027-m\u0027 a.k.a.\n\u0027--membind\u0027 because it allows multiple nodes to be specified\nand it\u0027s easy to type]--we can allocate huge pages on\nindividual nodes or sets of nodes. So, starting from the\ncondition above, with 8 huge pages per node, add 8 more to\nnode 2 using:\n\n\tnumactl -m 2 sysctl vm.nr_hugepages_mempolicy\u003d40\n\nThis yields:\n\n\tNode 0 HugePages_Total: 8\n\tNode 1 HugePages_Total: 8\n\tNode 2 HugePages_Total: 16\n\tNode 3 HugePages_Total: 8\n\nThe incremental 8 huge pages were restricted to node 2 by the\nspecified mempolicy.\n\nSimilarly, we can use mempolicy to free persistent huge pages\nfrom specified nodes:\n\n\tnumactl -m 0,1 sysctl vm.nr_hugepages_mempolicy\u003d32\n\nyields:\n\n\tNode 0 HugePages_Total: 4\n\tNode 1 HugePages_Total: 4\n\tNode 2 HugePages_Total: 16\n\tNode 3 HugePages_Total: 8\n\nThe 8 huge pages freed were balanced over nodes 0 and 1.\n\n[rientjes@google.com: accomodate reworked NODEMASK_ALLOC]\nSigned-off-by:

With pending\ncode like hw-breakpoints support the \u0027counter\u0027 name is less and\nless appropriate.\n\nAll in one, we\u0027ve decided to rename the subsystem to \u0027performance\nevents\u0027 and to propagate this rename through all fields, variables\nand API names. (in an ABI compatible fashion)\n\nThe word \u0027event\u0027 is also a bit shorter than \u0027counter\u0027 - which makes\nit slightly more convenient to write/handle as well.\n\nThanks goes to Stephane Eranian who first observed this misnomer and\nsuggested a rename.\n\nUser-space tooling and ABI compatibility is not affected - this patch\nshould be function-invariant.

The goal is to prevent everyone\nfrom accessing these pages in the future.\n\nThis done at the VM level by marking a page hwpoisoned\nand doing the appropriate action based on the type of page\nit is.\n\nThe code that does this is portable and lives in mm/memory-failure.c\n\nTo quote the overview comment:\n\nHigh level machine check handler. Handles pages reported by the\nhardware as being corrupted usually due to a 2bit ECC memory or cache\nfailure.\n\nThis focuses on pages detected as corrupted in the background.\nWhen the current CPU tries to consume corruption the currently\nrunning process can just be killed directly instead. This implies\nthat if the error cannot be handled for some reason it\u0027s safe to\njust ignore it because no corruption has been consumed yet. Instead\nwhen that happens another machine check will happen.\n\nHandles page cache pages in various states. The tricky part\nhere is that we can access any page asynchronous to other VM\nusers, because memory failures could happen anytime and anywhere,\npossibly violating some of their assumptions. This is why this code\nhas to be extremely careful. Generally it tries to use normal locking\nrules, as in get the standard locks, even if that means the\nerror handling takes potentially a long time.\n\nSome of the operations here are somewhat inefficient and have non\nlinear algorithmic complexity, because the data structures have not\nbeen optimized for this case. This is in particular the case\nfor the mapping from a vma to a process. Since this case is expected\nto be rare we hope we can get away with this.\n\nThere are in principle two strategies to kill processes on poison:\n- just unmap the data and wait for an actual reference before\nkilling\n- kill as soon as corruption is detected.\nBoth have advantages and disadvantages and should be used\nin different situations. Right now both are implemented and can\nbe switched with a new sysctl vm.memory_failure_early_kill\nThe default is early kill.\n\nThe patch does some rmap data structure walking on its own to collect\nprocesses to kill. This is unusual because normally all rmap data structure\nknowledge is in rmap.c only. I put it here for now to keep\neverything together and rmap knowledge has been seeping out anyways\n\nIncludes contributions from Johannes Weiner, Chris Mason, Fengguang Wu,\nNick Piggin (who did a

This allows finer control of pdflush\non both large and small machines.\n\nThe rationale is simply one size does not fit all. Admins on large and/or\nsmall systems may want to tune the min/max pdflush thread count to best\nsuit their needs. Right now the min/max is hardcoded to 2/8. While\nprobably a fair estimate for smaller machines, large machines with large\nnumbers of CPUs and large numbers of filesystems/block devices may benefit\nfrom larger numbers of threads working on different block devices.\n\nEven if the background flushing algorithm is radically changed, it is\nstill likely that multiple threads will be involved and admins would still\ndesire finer control on the min/max other than to have to recompile the\nkernel.\n\nThe patch adds \u0027/proc/sys/vm/nr_pdflush_threads_min\u0027 and\n\u0027/proc/sys/vm/nr_pdflush_threads_max\u0027 with r/w permissions.\n\nThe minimum value for nr_pdflush_threads_min is 1 and the maximum value is\nthe current value of nr_pdflush_threads_max. This minimum is required\nsince additional thread creation is performed in a pdflush thread itself.\n\nThe minimum value for nr_pdflush_threads_max is the current value of\nnr_pdflush_threads_min and the maximum value can be 1000.\n\nDocumentation/sysctl/vm.txt is also updated.\n\n[akpm@linux-foundation.org: fix comment, fix whitespace, use __read_mostly]\nSigned-off-by: Peter W Morreale \u003cpmorreale@novell.com\u003e\nReviewed-by: Rik van Riel \u003criel@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "5e34437840d33554f69380584311743b39e8fbeb", "tree": "e081135619ee146af5efb9ee883afca950df5757", "parents": [ "77d05632baee21b1cef8730d7c06aa69601e4dca", "d508afb437daee7cf07da085b635c44a4ebf9b38" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Apr 07 11:15:40 2009 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Apr 07 11:15:40 2009 +0200" }, "message": "Merge branch \u0027linus\u0027 into core/softlockup\n\nConflicts:\n\tkernel/sysctl.c\n" }, { "commit": "cd5f9a4c3199b090e91ea0064cb110985ba54814", "tree": "67d4da296ab85a96f28580420bf4cdef84d3aaaa", "parents": [ "609862be074cc20e007c640fd936ffe798b41abc" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Apr 06 13:38:46 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Apr 06 13:38:46 2009 -0700" }, "message": "kernel/sysctl.c: avoid annoying warnings\n\nSome of the limit constants are used only depending on some complex\nconfiguration dependencies, yet it\u0027s not worth making the simple\nvariables depend on those configuration details.

Vegard Nossum reported a very simple program (a modified\nversion attached) that can make a normal user to request a pretty large\namount of kernel memory, well within the its maximum number of fds. To\nsolve such problem, default limits are now imposed, and /proc based\nconfiguration has been introduced. A new directory has been created,\nnamed /proc/sys/fs/epoll/ and inside there, there are two configuration\npoints:\n\n max_user_instances \u003d Maximum number of devices - per user\n\n max_user_watches \u003d Maximum number of \"watched\" fds - per user\n\nThe current default for \"max_user_watches\" limits the memory used by epoll\nto store \"watches\", to 1/32 of the amount of the low RAM. As example, a\n256MB 32bit machine, will have \"max_user_watches\" set to roughly 90000.\nThat should be enough to not break existing heavy epoll users. The\ndefault value for \"max_user_instances\" is set to 128, that should be\nenough too.\n\nThis also changes the userspace, because a new error code can now come out\nfrom EPOLL_CTL_ADD (-ENOSPC).
