This infrastructure however has some\nshortcommings which can be enhanced. Specifically:\n\n1) The coredump code in the kernel should ignore RLIMIT_CORE limitation\n when core_pattern is a pipe, since file system resources are not being\n consumed in this case, unless the user application wishes to save the core,\n at which point the app is restricted by usual file system limits and\n restrictions.\n\n2) The core_pattern code should be able to parse and pass options to the\n user space helper as an argv array. The real core limit of the uid of the\n crashing proces should also be passable to the user space helper (since it\n is overridden to zero when called).\n\n3) Some miscellaneous bugs need to be cleaned up (specifically the\n recognition of a recursive core dump, should the user mode helper itself\n crash. Also, the core dump code in the kernel should not wait for the user\n mode helper to exit, since the same context is responsible for writing to\n the pipe, and a read of the pipe by the user mode helper will result in a\n deadlock.\n\nThis patch:\n\nRemove the check of RLIMIT_CORE if core_pattern is a pipe. In the event that\ncore_pattern is a pipe, the entire core will be fed to the user mode helper.\n\nSigned-off-by: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nCc: \u003cmartin.pitt@ubuntu.com\u003e\nCc: \u003cwwoods@redhat.com\u003e\nCc: Jeremy Fitzhardinge \u003cjeremy@goop.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "252e211e90ce56bf005cb533ad5a297c18c19407", "tree": "9b37f80e1f4c1ec74e150edb3ea7b8d70faea79a", "parents": [ "ef2fb67989d30fea475bb01c5b7ca44adbce5dea" ], "author": { "name": "Mark Fortescue", "email": "mark@mtfhpc.demon.co.uk", "time": "Tue Oct 16 23:26:31 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed Oct 17 08:42:49 2007 -0700" }, "message": "Add in SunOS 4.1.x compatible mode for UFS\n\nAdd in support for SunOS 4.1.x flavor of BSD 4.2 UFS filing system Macros have\nbeen put in to alow suport for the old static table Cylinder Groups but this\nimplementation does not use them yet.\n\nThis also fixes Solaris UFS filing system access by disabling fast symbolic\nlinks as Sun\u0027s version of UFS does not support on-disk fast symbolic links.\n\nTested by:\n Ppartitioning a new disk using SunOS 4.1.1, creating a UFS filing system on\n one of the partitions and writing some files to the filing system.\n Using Linux-2.6.22 (patched) to read the files and then write a shed load of\n files to the UFS partition.\n Using SunOS 4.1.1 to verify the filing system is OK and to check the files.\nThe test host is a sun4c SS1 Clone.\n\n[akpm@linux-foundation.org: coding style fixes]\n[adobriyan@gmail.com: fix oops]\nSigned-off-by: Mark Fortescue \u003cmark@mtfhpc.demon.co.uk\u003e\nCc: Evgeniy Dushistov \u003cdushistov@mail.ru\u003e\nSigned-off-by: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "74bf17cffc32511c7c6d70fe7f376b92662e186e", "tree": "e770b056d4a83f847a04fc92e119aa607ec0edaf", "parents": [ "1d99493b3a68e40e56459ea3565d4402fb6e5f3a" ], "author": { "name": "Denis Cheng", "email": "crquan@gmail.com", "time": "Tue Oct 16 23:26:30 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed Oct 17 08:42:49 2007 -0700" }, "message": "fs: remove the unused mempages parameter\n\nSince the mempages parameter is actually not used, they should be removed.\n\nNow there is only files_init use the mempages parameter,\n\n \tfiles_init(mempages);\n\nbut I don\u0027t think the adaptation to mempages in files_init is really\nuseful; and if files_init also changed to the prototype void (*func)(void),\nthe wrapper vfs_caches_init would also not need the mempages parameter.\n\nSigned-off-by: Denis Cheng \u003ccrquan@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "af49d9248fca6f26cbdb01918334f71d9040df80", "tree": "5d6a7f4d5ca55ff17fbfc98cacac37be62c7a4a3", "parents": [ "d9c9bef1345e5d9258febce2a37e4d40319fa728" ], "author": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Tue Oct 16 23:26:27 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed Oct 17 08:42:49 2007 -0700" }, "message": "Remove \"unsafe\" from module struct\n\nAdrian Bunk points out that \"unsafe\" was used to mark modules touched by\nthe deprecated MOD_INC_USE_COUNT interface, which has long gone.

This hook is also visible in userspace via the TIOCWINSZ, VT_RESIZE and\nVT_RESIZEX ioctl\u0027s. One particular utility, SVGATextMode, expects that\ncon_resize() of the VGA console will always return success even if the\nresulting screen is not compatible with the hardware. However, this\nparticular behavior of the VGA console, as reported in Kernel Bugzilla Bug\n7513, can cause undefined behavior if the user starts with a console size\nlarger than 80x25.\n\nTo work around this problem, add an extra parameter to con_resize(). This\nparameter is ignored by drivers except for vgacon. If this parameter is\nnon-zero, then the resize request came from a VT_RESIZE or VT_RESIZEX ioctl\nand vgacon will always return success.

One real time group did use it to\naffectively isolate CPUs from any load balancing efforts. They are willing\nto adapt to alternative mechanisms for this, such as someway to manipulate\nthe list of isolated CPUs on a running system. They can do without this\npresent cpu_exclusive based mechanism while we develop an alternative.\n\nThere is a real risk, to the best of my understanding, of users\naccidentally setting up a partitioned scheduler domains, inhibiting desired\nload balancing across all their CPUs, due to the nonobvious (from the\ncpuset perspective) side affects of the cpu_exclusive flag.\n\nFurthermore, since there was no way on a running system to see what one was\ndoing with sched domains, this change will be invisible to any using code.\nUnless they have real insight to the scheduler load balancing choices, they\nwill be unable to detect that this change has been made in the kernel\u0027s\nbehaviour.\n\nInitial discussion on lkml of this patch has generated much comment. My\n(probably controversial) take on that discussion is that it has reached a\nrough concensus that the current cpuset cpu_exclusive mechanism for\ndefining sched domains is borked. There is no concensus on the\nreplacement. But since we can remove this mechanism, and since its\ncontinued presence risks causing unwanted partitioning of the schedulers\nload balancing, we should remove it while we can, as we proceed to work the\nreplacement scheduler domain mechanisms.\n\nSigned-off-by: Paul Jackson \u003cpj@sgi.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nCc: Christoph Lameter \u003cclameter@engr.sgi.com\u003e\nCc: Dinakar Guniguntala \u003cdino@in.ibm.com\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "7589670f37736bcc119ebfbd69aafea6d585d1d4", "tree": "471f90dda6bcbcd59cc857b4f0130922bba88fc4", "parents": [ "3e037454bcfa4b187e8293d2121bd8c0f5a5c31c" ], "author": { "name": "Shannon Nelson", "email": "shannon.nelson@intel.com", "time": "Tue Oct 16 01:27:41 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Oct 16 09:43:09 2007 -0700" }, "message": "DCA: Add Direct Cache Access driver\n\nDirect Cache Access (DCA) is a method for warming the CPU cache before data\nis used, with the intent of lessening the impact of cache misses.

These are\nperformance critical structures since the per node information has\nto be touched for every alloc and free in a slab.\n\nIn order to place the kmem_cache_cpu structure optimally we put an array\nof pointers to kmem_cache_cpu structs in kmem_cache (similar to SLAB).\n\nHowever, the kmem_cache_cpu structures can now be allocated in a more\nintelligent way.\n\nWe would like to put per cpu structures for the same cpu but different\nslab caches in cachelines together to save space and decrease the cache\nfootprint. However, the slab allocators itself control only allocations\nper node. We set up a simple per cpu array for every processor with\n100 per cpu structures which is usually enough to get them all set up right.\nIf we run out then we fall back to kmalloc_node. This also solves the\nbootstrap problem since we do not have to use slab allocator functions\nearly in boot to get memory for the small per cpu structures.\n\nPro:\n\t- NUMA aware placement improves memory performance\n\t- All global structures in struct kmem_cache become readonly\n\t- Dense packing of per cpu structures reduces cacheline\n\t footprint in SMP and NUMA.\n\t- Potential avoidance of exclusive cacheline fetches\n\t on the free and alloc hotpath since multiple kmem_cache_cpu\n\t structures are in one cacheline.

If objects have a short lifetime and are freed by\na different processor then remote frees back to the slab from which we are\ncurrently allocating are frequent. The cacheline with the page struct needs\nto be repeately acquired in exclusive mode by both the allocating thread and\nthe freeing thread. If this is frequent enough then performance will suffer\nbecause of cacheline bouncing.\n\nThis patchset puts the lockless_freelist pointer in its own cacheline. In\norder to make that happen we introduce a per cpu structure called\nkmem_cache_cpu.\n\nInstead of keeping an array of pointers to page structs we now keep an array\nto a per cpu structure that--among other things--contains the pointer to the\nlockless freelist. The freeing thread can then keep possession of exclusive\naccess to the page struct cacheline while the allocating thread keeps its\nexclusive access to the cacheline containing the per cpu structure.\n\nThis works as long as the allocating cpu is able to service its request\nfrom the lockless freelist. If the lockless freelist runs empty then the\nallocating thread needs to acquire exclusive access to the cacheline with\nthe page struct lock the slab.\n\nThe allocating thread will then check if new objects were freed to the per\ncpu slab. If so it will keep the slab as the cpu slab and continue with the\nrecently remote freed objects. So the allocating thread can take a series\nof just freed remote pages and dish them out again. Ideally allocations\ncould be just recycling objects in the same slab this way which will lead\nto an ideal allocation / remote free pattern.\n\nThe number of objects that can be handled in this way is limited by the\ncapacity of one slab. Increasing slab size via slub_min_objects/\nslub_max_order may increase the number of objects and therefore performance.\n\nIf the allocating thread runs out of objects and finds that no objects were\nput back by the remote processor then it will retrieve a new slab (from the\npartial lists or from the page allocator) and start with a whole\nnew set of objects while the remote thread may still be freeing objects to\nthe old cpu slab. This may then repeat until the new slab is also exhausted.\nIf remote freeing has freed objects in the earlier slab then that earlier\nslab will now be on the partial freelist and the allocating thread will\npick that slab next for allocation. So the loop is extended. However,\nboth threads need to take the list_lock to make the swizzling via\nthe partial list happen.\n\nIt is likely that this kind of scheme will keep the objects being passed\naround to a small set that can be kept in the cpu caches leading to increased\nperformance.\n\nMore code cleanups become possible:\n\n- Instead of passing a cpu we can now pass a kmem_cache_cpu structure around.\n Allows reducing the number of parameters to various functions.\n- Can define a new node_match() function for NUMA to encapsulate locality\n checks.\n\nEffect on allocations:\n\nCachelines touched before this patch:\n\n\tWrite:\tpage cache struct and first cacheline of object\n\nCachelines touched after this patch:\n\n\tWrite:\tkmem_cache_cpu cacheline and first cacheline of object\n\tRead: page cache struct (but see later patch that avoids touching\n\t\tthat cacheline)\n\nThe handling when the lockless alloc list runs empty gets to be a bit more\ncomplicated since another cacheline has now to be written to. But that is\nhalfway out of the hot path.\n\nEffect on freeing:\n\nCachelines touched before this patch:\n\n\tWrite: page_struct and first cacheline of object\n\nCachelines touched after this patch depending on how we free:\n\n Write(to cpu_slab):\tkmem_cache_cpu struct and first cacheline of object\n Write(to other):\tpage struct and first cacheline of object\n\n Read(to cpu_slab):\tpage struct to id slab etc. (but see later patch that\n \t\t\tavoids touching the page struct on free)\n Read(to other):\tcpu local kmem_cache_cpu struct to verify its not\n \t\t\tthe cpu slab.\n\nSummary:\n\nPro:\n\t- Distinct cachelines so that concurrent remote frees and local\n\t allocs on a cpuslab can occur without cacheline bouncing.\n\t- Avoids potential bouncing cachelines because of neighboring\n\t per cpu pointer updates in kmem_cache\u0027s cpu_slab structure since\n\t it now grows to a cacheline (Therefore remove the comment\n\t that talks about that concern).\n\nCons:\n\t- Freeing objects now requires the reading of one additional\n\t cacheline. That can be mitigated for some cases by the following\n\t patches but its not possible to completely eliminate these\n\t references.\n\n\t- Memory usage grows slightly.\n\n\tThe size of each per cpu object is blown up from one word\n\t(pointing to the page_struct) to one cacheline with various data.\n\tSo this is NR_CPUS*NR_SLABS*L1_BYTES more memory use. Lets say\n\tNR_SLABS is 100 and a cache line size of 128 then we have just\n\tincreased SLAB metadata requirements by 12.8k per cpu.\n\t(Another later patch reduces these requirements)\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": "467c996c1e1910633fa8e7adc9b052aa3ed5f97c", "tree": "09e0e70160386be1bdaa12801afddf287e12c8a1", "parents": [ "d9c2340052278d8eb2ffb16b0484f8f794def4de" ], "author": { "name": "Mel Gorman", "email": "mel@csn.ul.ie", "time": "Tue Oct 16 01:26:02 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Oct 16 09:43:00 2007 -0700" }, "message": "Print out statistics in relation to fragmentation avoidance to /proc/pagetypeinfo\n\nThis patch provides fragmentation avoidance statistics via /proc/pagetypeinfo.\n The information is collected only on request so there is no runtime overhead.\n The statistics are in three parts:\n\nThe first part prints information on the size of blocks that pages are\nbeing grouped on and looks like\n\nPage block order: 10\nPages per block: 1024\n\nThe second part is a more detailed version of /proc/buddyinfo and looks like\n\nFree pages count per migrate type at order 0 1 2 3 4 5 6 7 8 9 10\nNode 0, zone DMA, type Unmovable 0 0 0 0 0 0 0 0 0 0 0\nNode 0, zone DMA, type Reclaimable 1 0 0 0 0 0 0 0 0 0 0\nNode 0, zone DMA, type Movable 0 0 0 0 0 0 0 0 0 0 0\nNode 0, zone DMA, type Reserve 0 4 4 0 0 0 0 1 0 1 0\nNode 0, zone Normal, type Unmovable 111 8 4 4 2 3 1 0 0 0 0\nNode 0, zone Normal, type Reclaimable 293 89 8 0 0 0 0 0 0 0 0\nNode 0, zone Normal, type Movable 1 6 13 9 7 6 3 0 0 0 0\nNode 0, zone Normal, type Reserve 0 0 0 0 0 0 0 0 0 0 4\n\nThe third part looks like\n\nNumber of blocks type Unmovable Reclaimable Movable Reserve\nNode 0, zone DMA 0 1 2 1\nNode 0, zone Normal 3 17 94 4\n\nTo walk the zones within a node with interrupts disabled, walk_zones_in_node()\nis introduced and shared between /proc/buddyinfo, /proc/zoneinfo and\n/proc/pagetypeinfo to reduce code duplication.
