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" }, { "commit": "74cb21553f4bf244185b9bec4c26e4e3169ad55e", "tree": "3f8f13e8dacc8f0876b01f62765a123ce1722b17", "parents": [ "909d75a3b77bdd8baa9429bad3b69a654d2954ce" ], "author": { "name": "Paul Jackson", "email": "pj@sgi.com", "time": "Sun Jan 08 01:01:56 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Jan 08 20:13:44 2006 -0800" }, "message": "[PATCH] cpuset: numa_policy_rebind cleanup\n\nCleanup, reorganize and make more robust the mempolicy.c code to rebind\nmempolicies relative to the containing cpuset after a tasks memory placement\nchanges.\n\nThe real motivator for this cleanup patch is to lay more groundwork for the\nupcoming patch to correctly rebind NUMA mempolicies that are attached to vma\u0027s\nafter the containing cpuset memory placement changes.\n\nNUMA mempolicies are constrained by the cpuset their task is a member of.\nWhen either (1) a task is moved to a different cpuset, or (2) the \u0027mems\u0027\nmems_allowed of a cpuset is changed, then the NUMA mempolicies have embedded\nnode numbers (for MPOL_BIND, MPOL_INTERLEAVE and MPOL_PREFERRED) that need to\nbe recalculated, relative to their new cpuset placement.\n\nThe old code used an unreliable method of determining what was the old\nmems_allowed constraining the mempolicy.

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(). Needed for swap\nmigration.\n\nSigned-off-by: Magnus Damm \u003cmagnus.damm@gmail.com\u003e\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" }, { "commit": "48db57f8ff10eb09ab887ccb6150b0da0c7be24e", "tree": "5c9fba3937bb802aa2944af189aae57b7bf7aa8b", "parents": [ "23316bc86fd31c5d644a71c398ec41d9fecacec4" ], "author": { "name": "Nick Piggin", "email": "nickpiggin@yahoo.com.au", "time": "Sun Jan 08 01:00:42 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Jan 08 20:12:40 2006 -0800" }, "message": "[PATCH] mm: free_pages opt\n\nTry to streamline free_pages_bulk by ensuring callers don\u0027t pass in a\n\u0027count\u0027 that exceeds the list size.\n\nSome cleanups:\nRename __free_pages_bulk to __free_one_page.\nPut the page list manipulation from __free_pages_ok into free_one_page.\nMake __free_pages_ok static.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "23316bc86fd31c5d644a71c398ec41d9fecacec4", "tree": "9efc5bbd9dd7c35b6b5fea8ce8215477c2ff43dd", "parents": [ "8ad4b1fb8205340dba16b63467bb23efc27264d6" ], "author": { "name": "Nick Piggin", "email": "nickpiggin@yahoo.com.au", "time": "Sun Jan 08 01:00:41 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Jan 08 20:12:40 2006 -0800" }, "message": "[PATCH] mm: cleanup zone_pcp\n\nUse zone_pcp everywhere even though NUMA code \"knows\" the internal details\nof the zone.

Say, we\u0027re scanning at high priority and suddenly\n hit a large number of reclaimable pages on the LRU.\n\n Change things so we bale out when SWAP_CLUSTER_MAX pages have been\n reclaimed.\n\nProblem is, this change caused significant imbalance in inter-zone scan\nbalancing by truncating scans of larger zones.\n\nSuppose, for example, ZONE_HIGHMEM is 10x the size of ZONE_NORMAL. The zone\nbalancing algorithm would require that if we\u0027re scanning 100 pages of\nZONE_HIGHMEM, we should scan 10 pages of ZONE_NORMAL. But this logic will\ncause the scanning of ZONE_HIGHMEM to bale out after only 32 pages are\nreclaimed. Thus effectively causing smaller zones to be scanned relatively\nharder than large ones.\n\nNow I need to remember what the workload was which caused me to write this\npatch originally, then fix it up in a different way...\n\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "41e9b63b35b52cf918a4ffdb8d77862ab824aa8b", "tree": "472ef8bb097f4e090f5fc95100acdbc77f515087", "parents": [ "9617d95e6e9ffd883cf90a89724fe60d7ab22f9a" ], "author": { "name": "Nick Piggin", "email": "nickpiggin@yahoo.com.au", "time": "Fri Jan 06 00:11:13 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jan 06 08:33:27 2006 -0800" }, "message": "[PATCH] mm: pfault optimisation\n\nThis atomic operation is superfluous: the pte will be added with the\nreferenced bit set, and the page will be referenced through this mapping after\nthe page fault handler returns anyway.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "9617d95e6e9ffd883cf90a89724fe60d7ab22f9a", "tree": "67d555d34d931bd253fbc4959ffdb1e5b904f2b0", "parents": [ "224abf92b2f439a9030f21d2926ec8047d1ffcdb" ], "author": { "name": "Nick Piggin", "email": "nickpiggin@yahoo.com.au", "time": "Fri Jan 06 00:11:12 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jan 06 08:33:27 2006 -0800" }, "message": "[PATCH] mm: rmap optimisation\n\nOptimise rmap functions by minimising atomic operations when we know there\nwill be no concurrent modifications.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "224abf92b2f439a9030f21d2926ec8047d1ffcdb", "tree": "e45074383aea04ef8b3b8d2cc04a3b34959f9e65", "parents": [ "9328b8faae922e52073785ed6c1eaa8565648a0e" ], "author": { "name": "Nick Piggin", "email": "nickpiggin@yahoo.com.au", "time": "Fri Jan 06 00:11:11 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jan 06 08:33:26 2006 -0800" }, "message": "[PATCH] mm: bad_page optimisation\n\nCut down size slightly by not passing bad_page the function name (it should be\nable to be determined by dump_stack()).

This helps us to safely use hugetlb pages in many more\napplications. The patch makes the following changes. If needed, I also have\nit broken out according to the following paragraphs.\n\n1. Add a pair of functions to set/clear write access on huge ptes. The\n writable check in make_huge_pte is moved out to the caller for use by COW\n later.\n\n2. Hugetlb copy-on-write requires special case handling in the following\n situations:\n\n - copy_hugetlb_page_range() - Copied pages must be write protected so\n a COW fault will be triggered (if necessary) if those pages are written\n to.\n\n - find_or_alloc_huge_page() - Only MAP_SHARED pages are added to the\n page cache.

Current\nimplementation supports only shmfs/tmpfs and other filesystems return\n-ENOSYS.\n\n\"Some app allocates large tmpfs files, then when some task quits and some\nclient disconnect, some memory can be released. However the only way to\nrelease tmpfs-swap is to MADV_REMOVE\". - Andrea Arcangeli\n\nDatabases want to use this feature to drop a section of their bufferpool\n(shared memory segments) - without writing back to disk/swap space.\n\nThis feature is also useful for supporting hot-plug memory on UML.\n\nConcerns raised by Andrew Morton:\n\n- \"We have no plan for holepunching! If we _do_ have such a plan (or\n might in the future) then what would the API look like? I think\n sys_holepunch(fd, start, len), so we should start out with that.\"\n\n- Using madvise is very weird, because people will ask \"why do I need to\n mmap my file before I can stick a hole in it?\"\n\n- None of the other madvise operations call into the filesystem in this\n manner. A broad question is: is this capability an MM operation or a\n filesytem operation? truncate, for example, is a filesystem operation\n which sometimes has MM side-effects. madvise is an mm operation and with\n this patch, it gains FS side-effects, only they\u0027re really, really\n significant ones.\"\n\nComments:\n\n- Andrea suggested the fs operation too but then it\u0027s more efficient to\n have it as a mm operation with fs side effects, because they don\u0027t\n immediatly know fd and physical offset of the range. It\u0027s possible to\n fixup in userland and to use the fs operation but it\u0027s more expensive,\n the vmas are already in the kernel and we can use them.\n\nShort term plan \u0026 Future Direction:\n\n- We seem to need this interface only for shmfs/tmpfs files in the short\n term. We have to add hooks into the filesystem for correctness and\n completeness. This is what this patch does.\n\n- In the future, plan is to support both fs and mmap apis also. This\n also involves (other) filesystem specific functions to be implemented.\n\n- Current patch doesn\u0027t support VM_NONLINEAR - which can be addressed in\n the future.\n\nSigned-off-by: Badari Pulavarty \u003cpbadari@us.ibm.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Andrea Arcangeli \u003candrea@suse.de\u003e\nCc: Michael Kerrisk \u003cmtk-manpages@gmx.net\u003e\nCc: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "d7339071f6a8b50101d7ba327926b770f22d5d8b", "tree": "051234ada89be22abb9ebbe4a541b16ade3bc2ff", "parents": [ "900b2b463dc6e65ec474d6880412c63c25b3aea9" ], "author": { "name": "Hans Reiser", "email": "reiser@namesys.com", "time": "Fri Jan 06 00:10:36 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jan 06 08:33:22 2006 -0800" }, "message": "[PATCH] reiser4: vfs: add truncate_inode_pages_range()\n\nThis patch makes truncate_inode_pages_range from truncate_inode_pages.\ntruncate_inode_pages became a one-liner call to truncate_inode_pages_range.\n\nReiser4 needs truncate_inode_pages_ranges because it tries to keep\ncorrespondence between existences of metadata pointing to data pages and pages\nto which those metadata point to.
