      "message": "[PATCH] NUMA slab locking fixes: fix cpu down and up locking\n\nThis fixes locking and bugs in cpu_down and cpu_up paths of the NUMA slab\nallocator.  Sonny Rao \u003csonny@burdell.org\u003e reported problems sometime back on\nPOWER5 boxes, when the last cpu on the nodes were being offlined.  We could\nnot reproduce the same on x86_64 because the cpumask (node_to_cpumask) was not\nbeing updated on cpu down.  Since that issue is now fixed, we can reproduce\nSonny\u0027s problems on x86_64 NUMA, and here is the fix.\n\nThe problem earlier was on CPU_DOWN, if it was the last cpu on the node to go\ndown, the array_caches (shared, alien) and the kmem_list3 of the node were\nbeing freed (kfree) with the kmem_list3 lock held.  If the l3 or the\narray_caches were to come from the same cache being cleared, we hit on\nbadness.\n\nThis patch cleans up the locking in cpu_up and cpu_down path.  We cannot\nreally free l3 on cpu down because, there is no node offlining yet and even\nthough a cpu is not yet up, node local memory can be allocated for it.  So l3s\nare usually allocated at keme_cache_create and destroyed at\nkmem_cache_destroy.  Hence, we don\u0027t need cachep-\u003espinlock protection to get\nto the cachep-\u003enodelist[nodeid] either.\n\nPatch survived onlining and offlining on a 4 core 2 node Tyan box with a 4\ndbench process running all the time.\n\nSigned-off-by: Alok N Kataria \u003calokk@calsoftinc.com\u003e\nSigned-off-by: Ravikiran Thirumalai \u003ckiran@scalex86.org\u003e\nCc: Christoph Lameter \u003cchristoph@lameter.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] NUMA policies in the slab allocator V2\n\nThis patch fixes a regression in 2.6.14 against 2.6.13 that causes an\nimbalance in memory allocation during bootup.\n\nThe slab allocator in 2.6.13 is not numa aware and simply calls\nalloc_pages().  This means that memory policies may control the behavior of\nalloc_pages().  During bootup the memory policy is set to MPOL_INTERLEAVE\nresulting in the spreading out of allocations during bootup over all\navailable nodes.  The slab allocator in 2.6.13 has only a single list of\nslab pages.  As a result the per cpu slab cache and the spinlock controlled\npage lists may contain slab entries from off node memory.  The slab\nallocator in 2.6.13 makes no effort to discern the locality of an entry on\nits lists.\n\nThe NUMA aware slab allocator in 2.6.14 controls locality of the slab pages\nexplicitly by calling alloc_pages_node().  The NUMA slab allocator manages\nslab entries by having lists of available slab pages for each node.  The\nper cpu slab cache can only contain slab entries associated with the node\nlocal to the processor.  This guarantees that the default allocation mode\nof the slab allocator always assigns local memory if available.\n\nSetting MPOL_INTERLEAVE as a default policy during bootup has no effect\nanymore.  In 2.6.14 all node unspecific slab allocations are performed on\nthe boot processor.  This means that most of key data structures are\nallocated on one node.  Most processors will have to refer to these\nstructures making the boot node a potential bottleneck.  This may reduce\nperformance and cause unnecessary memory pressure on the boot node.\n\nThis patch implements NUMA policies in the slab layer.  There is the need\nof explicit application of NUMA memory policies by the slab allcator itself\nsince the NUMA slab allocator does no longer let the page_allocator control\nlocality.\n\nThe check for policies is made directly at the beginning of __cache_alloc\nusing current-\u003emempolicy.  The memory policy is already frequently checked\nby the page allocator (alloc_page_vma() and alloc_page_current()).  So it\nis highly likely that the cacheline is present.  For MPOL_INTERLEAVE\nkmalloc() will spread out each request to one node after another so that an\nequal distribution of allocations can be obtained during bootup.\n\nIt is not possible to push the policy check to lower layers of the NUMA\nslab allocator since the per cpu caches are now only containing slab\nentries from the current node.  If the policy says that the local node is\nnot to be preferred or forbidden then there is no point in checking the\nslab cache or local list of slab pages.  The allocation better be directed\nimmediately to the lists containing slab entries for the allowed set of\nnodes.\n\nThis way of applying policy also fixes another strange behavior in 2.6.13.\nalloc_pages() is controlled by the memory allocation policy of the current\nprocess.  It could therefore be that one process is running with\nMPOL_INTERLEAVE and would f.e.  obtain a new page following that policy\nsince no slab entries are in the lists anymore.  A page can typically be\nused for multiple slab entries but lets say that the current process is\nonly using one.  The other entries are then added to the slab lists.  These\nare now non local entries in the slab lists despite of the possible\navailability of local pages that would provide faster access and increase\nthe performance of the application.\n\nAnother process without MPOL_INTERLEAVE may now run and expect a local slab\nentry from kmalloc().  However, there are still these free slab entries\nfrom the off node page obtained from the other process via MPOL_INTERLEAVE\nin the cache.  The process will then get an off node slab entry although\nother slab entries may be available that are local to that process.  This\nmeans that the policy if one process may contaminate the locality of the\nslab caches for other processes.\n\nThis patch in effect insures that a per process policy is followed for the\nallocation of slab entries and that there cannot be a memory policy\ninfluence from one process to another.  A process with default policy will\nalways get a local slab entry if one is available.  And the process using\nmemory policies will get its memory arranged as requested.  Off-node slab\nallocation will require the use of spinlocks and will make the use of per\ncpu caches not possible.  A process using memory policies to redirect\nallocations offnode will have to cope with additional lock overhead in\naddition to the latency added by the need to access a remote slab entry.\n\nChanges V1-\u003eV2\n- Remove #ifdef CONFIG_NUMA by moving forward declaration into\n  prior #ifdef CONFIG_NUMA section.\n\n- Give the function determining the node number to use a saner\n  name.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] Zone reclaim: Reclaim logic\n\nSome bits for zone reclaim exists in 2.6.15 but they are not usable.  This\npatch fixes them up, removes unused code and makes zone reclaim usable.\n\nZone reclaim allows the reclaiming of pages from a zone if the number of\nfree pages falls below the watermarks even if other zones still have enough\npages available.  Zone reclaim is of particular importance for NUMA\nmachines.  It can be more beneficial to reclaim a page than taking the\nperformance penalties that come with allocating a page on a remote zone.\n\nZone reclaim is enabled if the maximum distance to another node is higher\nthan RECLAIM_DISTANCE, which may be defined by an arch.  By default\nRECLAIM_DISTANCE is 20.  20 is the distance to another node in the same\ncomponent (enclosure or motherboard) on IA64.  The meaning of the NUMA\ndistance information seems to vary by arch.\n\nIf zone reclaim is not successful then no further reclaim attempts will\noccur for a certain time period (ZONE_RECLAIM_INTERVAL).\n\nThis patch was discussed before.

      "message": "[PATCH] cpuset: rebind vma mempolicies fix\n\nFix more of longstanding bug in cpuset/mempolicy interaction.\n\nNUMA mempolicies (mm/mempolicy.c) are constrained by the current tasks cpuset\nto just the Memory Nodes allowed by that cpuset.  The kernel maintains\ninternal state for each mempolicy, tracking what nodes are used for the\nMPOL_INTERLEAVE, MPOL_BIND or MPOL_PREFERRED policies.\n\nWhen a tasks cpuset memory placement changes, whether because the cpuset\nchanged, or because the task was attached to a different cpuset, then the\ntasks mempolicies have to be rebound to the new cpuset placement, so as to\npreserve the cpuset-relative numbering of the nodes in that policy.\n\nAn earlier fix handled such mempolicy rebinding for mempolicies attached to a\ntask.\n\nThis fix rebinds mempolicies attached to vma\u0027s (address ranges in a tasks\naddress space.) Due to the need to hold the task-\u003emm-\u003emmap_sem semaphore while\nupdating vma\u0027s, the rebinding of vma mempolicies has to be done when the\ncpuset memory placement is changed, at which time mmap_sem can be safely\nacquired.  The tasks mempolicy is rebound later, when the task next attempts\nto allocate memory and notices that its task-\u003ecpuset_mems_generation is\nout-of-date with its cpusets mems_generation.\n\nBecause walking the tasklist to find all tasks attached to a changing cpuset\nrequires holding tasklist_lock, a spinlock, one cannot update the vma\u0027s of the\naffected tasks while doing the tasklist scan.  In general, one cannot acquire\na semaphore (which can sleep) while already holding a spinlock (such as\ntasklist_lock).  So a list of mm references has to be built up during the\ntasklist scan, then the tasklist lock dropped, then for each mm, its mmap_sem\nacquired, and the vma\u0027s in that mm rebound.\n\nOnce the tasklist lock is dropped, affected tasks may fork new tasks, before\ntheir mm\u0027s are rebound.  A kernel global \u0027cpuset_being_rebound\u0027 is set to\npoint to the cpuset being rebound (there can only be one; cpuset modifications\nare done under a global \u0027manage_sem\u0027 semaphore), and the mpol_copy code that\nis used to copy a tasks mempolicies during fork catches such forking tasks,\nand ensures their children are also rebound.\n\nWhen a task is moved to a different cpuset, it is easier, as there is only one\ntask involved.  It\u0027s mm-\u003evma\u0027s are scanned, using the same\nmpol_rebind_policy() as used above.\n\nIt may happen that both the mpol_copy hook and the update done via the\ntasklist scan update the same mm twice.  This is ok, as the mempolicies of\neach vma in an mm keep track of what mems_allowed they are relative to, and\nsafely no-op a second request to rebind to the same nodes.\n\nSigned-off-by: Paul Jackson \u003cpj@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

It just looked at the tasks\nmems_allowed value.  This sort of worked with the present code, that just\nrebinds the -task- mempolicy, and leaves any -vma- mempolicies broken,\nreferring to the old nodes.  But in an upcoming patch, the vma mempolicies\nwill be rebound as well.  Then the order in which the various task and vma\nmempolicies are updated will no longer be deterministic, and one can no longer\ncount on the task-\u003emems_allowed holding the old value for as long as needed.\nIt\u0027s not even clear if the current code was guaranteed to work reliably for\ntask mempolicies.\n\nSo I added a mems_allowed field to each mempolicy, stating exactly what\nmems_allowed the policy is relative to, and updated synchronously and reliably\nanytime that the mempolicy is rebound.\n\nAlso removed a useless wrapper routine, numa_policy_rebind(), and had its\ncaller, cpuset_update_task_memory_state(), call directly to the rewritten\npolicy_rebind() routine, and made that rebind routine extern instead of\nstatic, and added a \"mpol_\" prefix to its name, making it\nmpol_rebind_policy().\n\nSigned-off-by: Paul Jackson \u003cpj@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

It uses per-arch L1_CACHE_SHIFT_MAX and people find\nL1_CACHE_SHIFT_MAX useless.\n\nHowever, we have been using ____cacheline_maxaligned_in_smp to align\nstructures on the internode cacheline size.  As per Andi\u0027s suggestion,\nfollowing patch kills ____cacheline_maxaligned_in_smp and introduces\nINTERNODE_CACHE_SHIFT, which defaults to L1_CACHE_SHIFT for all arches.\nArches needing L3/Internode cacheline alignment can define\nINTERNODE_CACHE_SHIFT in the arch asm/cache.h.

A process may\nhave migrated to another node.  Memory was allocated optimally for the prior\ncontext.  sys_migrate_pages allows to shift the memory to the new node.\n\nsys_migrate_pages is also useful if the processes available memory nodes have\nchanged through cpuset operations to manually move the processes memory.  Paul\nJackson is working on an automated mechanism that will allow an automatic\nmigration if the cpuset of a process is changed.  However, a user may decide\nto manually control the migration.\n\nThis implementation is put into the policy layer since it uses concepts and\nfunctions that are also needed for mbind and friends.  The patch also provides\na do_migrate_pages function that may be useful for cpusets to automatically\nmove memory.  sys_migrate_pages does not modify policies in contrast to Ray\u0027s\nimplementation.\n\nThe current code here is based on the swap based page migration capability and\nthus is not able to preserve the physical layout relative to it containing\nnodeset (which may be a cpuset).  When direct page migration becomes available\nthen the implementation needs to be changed to do a isomorphic move of pages\nbetween different nodesets.  The current implementation simply evicts all\npages in source nodeset that are not in the target nodeset.\n\nPatch supports ia64, i386 and x86_64.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] Swap Migration V5: LRU operations\n\nThis is the start of the `swap migration\u0027 patch series.\n\nSwap migration allows the moving of the physical location of pages between\nnodes in a numa system while the process is running.  This means that the\nvirtual addresses that the process sees do not change.  However, the system\nrearranges the physical location of those pages.\n\nThe main intent of page migration patches here is to reduce the latency of\nmemory access by moving pages near to the processor where the process\naccessing that memory is running.\n\nThe patchset allows a process to manually relocate the node on which its\npages are located through the MF_MOVE and MF_MOVE_ALL options while\nsetting a new memory policy.\n\nThe pages of process can also be relocated from another process using the\nsys_migrate_pages() function call.  Requires CAP_SYS_ADMIN.  The migrate_pages\nfunction call takes two sets of nodes and moves pages of a process that are\nlocated on the from nodes to the destination nodes.\n\nManual migration is very useful if for example the scheduler has relocated a\nprocess to a processor on a distant node.  A batch scheduler or an\nadministrator can detect the situation and move the pages of the process\nnearer to the new processor.\n\nsys_migrate_pages() could be used on non-numa machines as well, to force all\nof a particualr process\u0027s pages out to swap, if someone thinks that\u0027s useful.\n\nLarger installations usually partition the system using cpusets into sections\nof nodes.  Paul has equipped cpusets with the ability to move pages when a\ntask is moved to another cpuset.  This allows automatic control over locality\nof a process.  If a task is moved to a new cpuset then also all its pages are\nmoved with it so that the performance of the process does not sink\ndramatically (as is the case today).\n\nSwap migration works by simply evicting the page.  The pages must be faulted\nback in.  The pages are then typically reallocated by the system near the node\nwhere the process is executing.\n\nFor swap migration the destination of the move is controlled by the allocation\npolicy.  Cpusets set the allocation policy before calling sys_migrate_pages()\nin order to move the pages as intended.\n\nNo allocation policy changes are performed for sys_migrate_pages().  This\nmeans that the pages may not faulted in to the specified nodes if no\nallocation policy was set by other means.  The pages will just end up near the\nnode where the fault occurred.\n\nThere\u0027s another patch series in the pipeline which implements \"direct\nmigration\".\n\nThe direct migration patchset extends the migration functionality to avoid\ngoing through swap.  The destination node of the relation is controllable\nduring the actual moving of pages.  The crutch of using the allocation policy\nto relocate is not necessary and the pages are moved directly to the target.\nIts also faster since swap is not used.\n\nAnd sys_migrate_pages() can then move pages directly to the specified node.\nImplement functions to isolate pages from the LRU and put them back later.\n\nThis patch:\n\nAn earlier implementation was provided by Hirokazu Takahashi\n\u003ctaka@valinux.co.jp\u003e and IWAMOTO Toshihiro \u003ciwamoto@valinux.co.jp\u003e for the\nmemory hotplug project.\n\nFrom: Magnus\n\nThis breaks out isolate_lru_page() and putpack_lru_page().

      "message": "[PATCH] Make high and batch sizes of per_cpu_pagelists configurable\n\nAs recently there has been lot of traffic on the right values for batch and\nhigh water marks for per_cpu_pagelists.  This patch makes these two\nvariables configurable through /proc interface.\n\nA new tunable /proc/sys/vm/percpu_pagelist_fraction is added.  This entry\ncontrols the fraction of pages at most in each zone that are allocated for\neach per cpu page list.  The min value for this is 8.  It means that we\ndon\u0027t allow more than 1/8th of pages in each zone to be allocated in any\nsingle per_cpu_pagelist.\n\nThe batch value of each per cpu pagelist is also updated as a result.  It\nis set to pcp-\u003ehigh/4.  The upper limit of batch is (PAGE_SHIFT * 8)\n\nSigned-off-by: Rohit Seth \u003crohit.seth@intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
