      "message": "[PATCH] Fix slab BUG_ON() triggered by change in array cache size\n\nWith the new changes that we made in the initialization of the slab\nallocator, we first setup the cache from which array caches are allocated,\nand then the cache, from which kmem_list3\u0027s are allocated.\n\nNow if the array cache comes from a cache in which objsize \u003e 32, (in this\ninstance size-64) then, first size-64 cache will be allocated and then the\nsize-128 (if this is the cache from which kmem_list3\u0027s are going to be\nallocated).\n\nSo with these new changes, we are not guaranteed that we will be\ninitializing the malloc_sizes array in a serialized order. Thus there is\na bug in __find_general_cachep, as we are checking whether the first\ncache_sizes ptr is NULL.\n\nThis is replaced by checking whether the array-cache cache is initialized.\nAttached is a patch which does that.  Boots fine on a x86-64, with\nDEBUG_SPIN, DEBUG_SLAB, and preempt.\n\nAttached is a patch which does that.

      "message": "[PATCH] Numa-aware slab allocator V5\n\nThe NUMA API change that introduced kmalloc_node was accepted for\n2.6.12-rc3.  Now it is possible to do slab allocations on a node to\nlocalize memory structures.  This API was used by the pageset localization\npatch and the block layer localization patch now in mm.  The existing\nkmalloc_node is slow since it simply searches through all pages of the slab\nto find a page that is on the node requested.  The two patches do a one\ntime allocation of slab structures at initialization and therefore the\nspeed of kmalloc node does not matter.\n\nThis patch allows kmalloc_node to be as fast as kmalloc by introducing node\nspecific page lists for partial, free and full slabs.  Slab allocation\nimproves in a NUMA system so that we are seeing a performance gain in AIM7\nof about 5% with this patch alone.\n\nMore NUMA localizations are possible if kmalloc_node operates in an fast\nway like kmalloc.\n\nTest run on a 32p systems with 32G Ram.\n\nw/o patch\nTasks    jobs/min  jti  jobs/min/task      real       cpu\n    1      485.36  100       485.3640     11.99      1.91   Sat Apr 30 14:01:51 2005\n  100    26582.63   88       265.8263     21.89    144.96   Sat Apr 30 14:02:14 2005\n  200    29866.83   81       149.3342     38.97    286.08   Sat Apr 30 14:02:53 2005\n  300    33127.16   78       110.4239     52.71    426.54   Sat Apr 30 14:03:46 2005\n  400    34889.47   80        87.2237     66.72    568.90   Sat Apr 30 14:04:53 2005\n  500    35654.34   76        71.3087     81.62    714.55   Sat Apr 30 14:06:15 2005\n  600    36460.83   75        60.7681     95.77    853.42   Sat Apr 30 14:07:51 2005\n  700    35957.00   75        51.3671    113.30    990.67   Sat Apr 30 14:09:45 2005\n  800    33380.65   73        41.7258    139.48   1140.86   Sat Apr 30 14:12:05 2005\n  900    35095.01   76        38.9945    149.25   1281.30   Sat Apr 30 14:14:35 2005\n 1000    36094.37   74        36.0944    161.24   1419.66   Sat Apr 30 14:17:17 2005\n\nw/patch\nTasks    jobs/min  jti  jobs/min/task      real       cpu\n    1      484.27  100       484.2736     12.02      1.93   Sat Apr 30 15:59:45 2005\n  100    28262.03   90       282.6203     20.59    143.57   Sat Apr 30 16:00:06 2005\n  200    32246.45   82       161.2322     36.10    282.89   Sat Apr 30 16:00:42 2005\n  300    37945.80   83       126.4860     46.01    418.75   Sat Apr 30 16:01:28 2005\n  400    40000.69   81       100.0017     58.20    561.48   Sat Apr 30 16:02:27 2005\n  500    40976.10   78        81.9522     71.02    696.95   Sat Apr 30 16:03:38 2005\n  600    41121.54   78        68.5359     84.92    834.86   Sat Apr 30 16:05:04 2005\n  700    44052.77   78        62.9325     92.48    971.53   Sat Apr 30 16:06:37 2005\n  800    41066.89   79        51.3336    113.38   1111.15   Sat Apr 30 16:08:31 2005\n  900    38918.77   79        43.2431    134.59   1252.57   Sat Apr 30 16:10:46 2005\n 1000    41842.21   76        41.8422    139.09   1392.33   Sat Apr 30 16:13:05 2005\n\nThese are measurement taken directly after boot and show a greater\nimprovement than 5%.

With this patch, there are now the following four layers of\nmemory placement available:\n\n 1) The whole system (interrupt and GFP_ATOMIC allocations can use this),\n 2) The nearest enclosing mem_exclusive cpuset (GFP_KERNEL allocations can use),\n 3) The current tasks cpuset (GFP_USER allocations constrained to here), and\n 4) Specific node placement, using mbind and set_mempolicy.\n\nThese nest - each layer is a subset (same or within) of the previous.\n\nLayer (2) above is new, with this patch.  The call used to check whether a\nzone (its node, actually) is in a cpuset (in its mems_allowed, actually) is\nextended to take a gfp_mask argument, and its logic is extended, in the case\nthat __GFP_HARDWALL is not set in the flag bits, to look up the cpuset\nhierarchy for the nearest enclosing mem_exclusive cpuset, to determine if\nplacement is allowed.  The definition of GFP_USER, which used to be identical\nto GFP_KERNEL, is changed to also set the __GFP_HARDWALL bit, in the previous\ncpuset_gfp_hardwall_flag patch.\n\nGFP_ATOMIC and GFP_KERNEL allocations will stay within the current tasks\ncpuset, so long as any node therein is not too tight on memory, but will\nescape to the larger layer, if need be.\n\nThe intended use is to allow something like a batch manager to handle several\njobs, each job in its own cpuset, but using common kernel memory for caches\nand such.  Swapper and oom_kill activity is also constrained to Layer (2).  A\ntask in or below one mem_exclusive cpuset should not cause swapping on nodes\nin another non-overlapping mem_exclusive cpuset, nor provoke oom_killing of a\ntask in another such cpuset.  Heavy use of kernel memory for i/o caching and\nsuch by one job should not impact the memory available to jobs in other\nnon-overlapping mem_exclusive cpusets.\n\nThis patch enables providing hardwall, inescapable cpusets for memory\nallocations of each job, while sharing kernel memory allocations between\nseveral jobs, in an enclosing mem_exclusive cpuset.\n\nLike Dinakar\u0027s patch earlier to enable administering sched domains using the\ncpu_exclusive flag, this patch also provides a useful meaning to a cpuset flag\nthat had previously done nothing much useful other than restrict what cpuset\nconfigurations were allowed.\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"

For a few hours or more, a large NUMA\nsystem at a University is to be divided in two halves, with a bunch of student\njobs running in half the system under some form of batch manager, and with a\nbig research project running in the other half.  Each of the student jobs is\nplaced in a small cpuset, but should share the classic Unix time share\nfacilities, such as buffered pages of files in /bin and /usr/lib.  The big\nresearch project wants no interference whatsoever from the student jobs, and\nhas highly tuned, unusual memory and i/o patterns that intend to make full use\nof all the main memory on the nodes available to it.\n\nIn this example, we have two big sibling cpusets, one of which is further\ndivided into a more dynamic set of child cpusets.\n\nWe want kernel memory allocations constrained by the two big cpusets, and user\nallocations constrained by the smaller child cpusets where present.  And we\nrequire that the oom killer not operate across the two halves of this system,\nor else the first time a student job runs amuck, the big research project will\nlikely be first inline to get shot.\n\nTweaking /proc/\u003cpid\u003e/oom_adj is not ideal -- if the big research project\nreally does run amuck allocating memory, it should be shot, not some other\ntask outside the research projects mem_exclusive cpuset.\n\nI propose to extend the use of the \u0027mem_exclusive\u0027 flag of cpusets to manage\nsuch scenarios.  Let memory allocations for user space (GFP_USER) be\nconstrained by a tasks current cpuset, but memory allocations for kernel space\n(GFP_KERNEL) by constrained by the nearest mem_exclusive ancestor of the\ncurrent cpuset, even though kernel space allocations will still _prefer_ to\nremain within the current tasks cpuset, if memory is easily available.\n\nLet the oom killer be constrained to consider only tasks that are in\noverlapping mem_exclusive cpusets (it won\u0027t help much to kill a task that\nnormally cannot allocate memory on any of the same nodes as the ones on which\nthe current task can allocate.)\n\nThe current constraints imposed on setting mem_exclusive are unchanged.  A\ncpuset may only be mem_exclusive if its parent is also mem_exclusive, and a\nmem_exclusive cpuset may not overlap any of its siblings memory nodes.\n\nThis patch was presented on linux-mm in early July 2005, though did not\ngenerate much feedback at that time.  It has been built for a variety of\narch\u0027s using cross tools, and built, booted and tested for function on SN2\n(ia64).\n\nThere are 4 patches in this set:\n  1) Some minor cleanup, and some improvements to the code layout\n     of one routine to make subsequent patches cleaner.\n  2) Add another GFP flag - __GFP_HARDWALL.  It marks memory\n     requests for USER space, which are tightly confined by the\n     current tasks cpuset.\n  3) Now memory requests (such as KERNEL) that not marked HARDWALL can\n     if short on memory, look in the potentially larger pool of memory\n     defined by the nearest mem_exclusive ancestor cpuset of the current\n     tasks cpuset.\n  4) Finally, modify the oom killer to skip any task whose mem_exclusive\n     cpuset doesn\u0027t overlap ours.\n\nPatch (1), the one time I looked on an SN2 (ia64) build, actually saved 32\nbytes of kernel text space.  Patch (2) has no affect on the size of kernel\ntext space (it just adds a preprocessor flag).  Patches (3) and (4) added\nabout 600 bytes each of kernel text space, mostly in kernel/cpuset.c, which\nmatters only if CONFIG_CPUSET is enabled.\n\nThis patch:\n\nThis patch applies a few comment and code cleanups to mm/oom_kill.c prior to\napplying a few small patches to improve cpuset management of memory placement.\n\nThe comment changed in oom_kill.c was seriously misleading.  The code layout\nchange in select_bad_process() makes room for adding another condition on\nwhich a process can be spared the oom killer (see the subsequent\ncpuset_nodes_overlap patch for this addition).\n\nAlso a couple typos and spellos that bugged me, while I was here.\n\nThis patch should have no material affect.\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"

This allows security modules to export the incore\ninode security label information to userspace even if the filesystem does\nnot provide xattr storage, and eliminates the need to individually patch\nvarious pseudo filesystem types to provide such access.  The patch removes\nthe existing xattr code from devpts and tmpfs as it is then no longer\nneeded.\n\nThe patch restructures the code flow slightly to reduce duplication between\nthe normal path and the fallback path, but this should only have one\nuser-visible side effect - a program may get -EACCES rather than\n-EOPNOTSUPP if policy denied access but the filesystem didn\u0027t support the\noperation anyway.  Note that the post_setxattr hook call is not needed in\nthe fallback case, as the inode_setsecurity hook call handles the incore\ninode security state update directly.

It happens\n\u003e if the virtual address for hugetlb mmap is recycled from previously used\n\u003e normal page mmap. free_pgtables() might not scrub the pmd entry on\n\u003e munmap and hugetlb_prefault skips on any pmd presence regardless what type\n\u003e it is.\n\nUnless I am missing something, it seems more correct to place the check inside\nhuge_pte_alloc() to prevent a the same bug wherever a huge pte is allocated.\nIt also allows checking for this condition when lazily faulting huge pages\nlater in the series.\n\nSigned-off-by: Adam Litke \u003cagl@us.ibm.com\u003e\nCc: \u003clinux-mm@kvack.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

In trying to add support for ioremap()\nof 36-bit I/O, we run into the issue that get_vm_area() allows for a\nmaximum of 512K alignment via the IOREMAP_MAX_ORDER constant.  To work\naround this, we can:\n\n- Allocate a larger VM area than needed (size + (1ul \u003c\u003c IOREMAP_MAX_ORDER))\n  and then align the pointer ourselves, but this ends up with 512K of\n  wasted VM per ioremap().\n\n- Provide a new __get_vm_area_aligned() API and make __get_vm_area() sit\n  on top of this. I did this and it works but I don\u0027t like the idea\n  adding another VM API just for this one case.\n\n- My preferred solution which is to allow the architecture to override\n  the IOREMAP_MAX_ORDER constant with it\u0027s own version.\n\nSigned-off-by: Deepak Saxena \u003cdsaxena@plexity.net\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] /proc/\u003cpid\u003e/numa_maps to show on which nodes pages reside\n\nThis patch was recently discussed on linux-mm:\nhttp://marc.theaimsgroup.com/?t\u003d112085728500002\u0026r\u003d1\u0026w\u003d2\n\nI inherited a large code base from Ray for page migration.  There was a\nsmall patch in there that I find to be very useful since it allows the\ndisplay of the locality of the pages in use by a process.  I reworked that\npatch and came up with a /proc/\u003cpid\u003e/numa_maps that gives more information\nabout the vma\u0027s of a process.  numa_maps is indexes by the start address\nfound in /proc/\u003cpid\u003e/maps.

      "message": "[PATCH] xip: reduce code duplication\n\nThis patch reworks filemap_xip.c with the goal to reduce code duplication\nfrom mm/filemap.c.  It applies agains 2.6.12-rc6-mm1.  Instead of\nimplementing the aio functions, this one implements the synchronous\nread/write functions only.  For readv and writev, the generic fallback is\nused.  For aio, we rely on the application doing the fallback.  Since our\n\"synchronous\" function does memcpy immediately anyway, there is no\nperformance difference between using the fallbacks or implementing each\noperation.\n\nSigned-off-by: Carsten Otte \u003ccotte@de.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
