The generic\nalgorithm instead merges pairs of equal length lists as early as possible,\nin recursive order. For either algorithm, the elements that extend the\nlist beyond power-of-two length are a special case, handled as nearly as\npossible as a \"rounding-up\" to a full POT.\n\nSome intuition for the locality of reference implications of merge order\nmay be gotten by watching this animation:\n\n http://www.sorting-algorithms.com/merge-sort\n\nSimon\u0027s algorithm requires only O(1) extra space rather than the generic\nalgorithm\u0027s O(log N), but in my non-recursive implementation the actual\nO(log N) data is merely a vector of ~20 pointers, which I\u0027ve put on the\nstack.\n\nLong-running list_sort() calls: If the list passed in may be long, or the\nclient\u0027s cmp() callback function is slow, the client\u0027s cmp() may\nperiodically invoke cond_resched() to voluntarily yield the CPU. All\ninner loops of list_sort() call back to cmp().\n\nStability of the sort: distinct elements that compare equal emerge from\nthe sort in the same order as with Mark\u0027s code, for simple test cases. A\nboot-time test is provided to verify this and other correctness\nrequirements.\n\nA kernel that uses drm.ko appears to run normally with this change; I have\nno suitable hardware to similarly test the use by UBIFS.\n\n[akpm@linux-foundation.org: style tweaks, fix comment, make list_sort_test __init]\nSigned-off-by: Don Mullis \u003cdon.mullis@gmail.com\u003e\nCc: Dave Airlie \u003cairlied@redhat.com\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Dave Chinner \u003cdavid@fromorbit.com\u003e\nCc: Artem Bityutskiy \u003cdedekind@infradead.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "d6a2eedfddcded92c8f9b0ac022a99c4134696b0", "tree": "6a0f38fbc74e839fc7712f8ebcb65cce75cdcc06", "parents": [ "a11d2b64e1f2556953120d516241243ea365f0ae" ], "author": { "name": "André Goddard Rosa", "email": "andre.goddard@gmail.com", "time": "Fri Mar 05 13:43:12 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Mar 06 11:26:35 2010 -0800" }, "message": "lib/string.c: simplify strnstr()\n\nSigned-off-by: André Goddard Rosa \u003candre.goddard@gmail.com\u003e\nCc: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nCc: Joe Perches \u003cjoe@perches.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@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": "a11d2b64e1f2556953120d516241243ea365f0ae", "tree": "efb406b16a33fedf9c239fd6c09d8fe74b0042b7", "parents": [ "8a6e25357d51d6ecf4ee21e9048f0416a085a79c" ], "author": { "name": "André Goddard Rosa", "email": "andre.goddard@gmail.com", "time": "Fri Mar 05 13:43:11 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Mar 06 11:26:35 2010 -0800" }, "message": "lib/string.c: simplify stricmp()\n\nRemoves 32 bytes on core2 with gcc 4.4.1:\n text data bss dec hex filename\n 3196 0 0 3196 c7c lib/string-BEFORE.o\n 3164 0 0 3164 c5c lib/string-AFTER.o\n\nSigned-off-by: André Goddard Rosa \u003candre.goddard@gmail.com\u003e\nCc: Joe Perches \u003cjoe@perches.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@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": "8a6e25357d51d6ecf4ee21e9048f0416a085a79c", "tree": "40cf59ac816f6dd07d7b775fc4d58b0469cf2bf1", "parents": [ "e200e0ec9148ad2941e30d59b9552973d49a82b6" ], "author": { "name": "Joe Perches", "email": "joe@perches.com", "time": "Fri Mar 05 13:43:11 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Mar 06 11:26:35 2010 -0800" }, "message": "MAINTAINERS: document and add \"Q\" patchwork queue entries\n\nPatchwork queues show the acceptance/rejection state of submitted patches\nfor various MAINTAINER trees.

When those pages dominate memory, the system\nno longer has a meaningful notion of \u0027working set\u0027 and is required\nto give up the active list to make reclaim progress. Obviously,\nthis results in rather bad scanning latencies and the wrong pages\nbeing reclaimed.\n\nThis patch makes the VM be more careful about activating mapped file\npages in the first place. The minimum granted lifetime without\nanother memory access becomes an inactive list cycle instead of the\nfull memory cycle, which is more natural given the mentioned loads.\n\nThis test resembles a hashing rtorrent process. Sequentially, 32MB\nchunks of a file are mapped into memory, hashed (sha1) and unmapped\nagain. While this happens, every 5 seconds a process is launched and\nits execution time taken:\n\n\tpython2.4 -c \u0027import pydoc\u0027\n\told: max\u003d2.31s mean\u003d1.26s (0.34)\n\tnew: max\u003d1.25s mean\u003d0.32s (0.32)\n\n\tfind /etc -type f\n\told: max\u003d2.52s mean\u003d1.44s (0.43)\n\tnew: max\u003d1.92s mean\u003d0.12s (0.17)\n\n\tvim -c \u0027:quit\u0027\n\told: max\u003d6.14s mean\u003d4.03s (0.49)\n\tnew: max\u003d3.48s mean\u003d2.41s (0.25)\n\n\tmplayer --help\n\told: max\u003d8.08s mean\u003d5.74s (1.02)\n\tnew: max\u003d3.79s mean\u003d1.32s (0.81)\n\n\toverall hash time (stdev):\n\told: time\u003d1192.30 (12.85) thruput\u003d25.78mb/s (0.27)\n\tnew: time\u003d1060.27 (32.58) thruput\u003d29.02mb/s (0.88) (-11%)\n\nI also tested kernbench with regular IO streaming in the background to\nsee whether the delayed activation of frequently used mapped file\npages had a negative impact on performance in the presence of pressure\non the inactive list. The patch made no significant difference in\ntiming, neither for kernbench nor for the streaming IO throughput.\n\nThe first patch submission raised concerns about the cost of the extra\nfaults for actually activated pages on machines that have no hardware\nsupport for young page table entries.\n\nI created an artificial worst case scenario on an ARM machine with\naround 300MHz and 64MB of memory to figure out the dimensions\ninvolved. The test would mmap a file of 20MB, then\n\n 1. touch all its pages to fault them in\n 2. force one full scan cycle on the inactive file LRU\n -- old: mapping pages activated\n -- new: mapping pages inactive\n 3. touch the mapping pages again\n -- old and new: fault exceptions to set the young bits\n 4. force another full scan cycle on the inactive file LRU\n 5. touch the mapping pages one last time\n -- new: fault exceptions to set the young bits\n\nThe test showed an overall increase of 6% in time over 100 iterations\nof the above (old: ~212sec, new: ~225sec). 13 secs total overhead /\n(100 * 5k pages), ignoring the execution time of the test itself,\nmakes for about 25us overhead for every page that gets actually\nactivated. Note:\n\n 1. File mapping the size of one third of main memory, _completely_\n in active use across memory pressure - i.e., most pages referenced\n within one LRU cycle. This should be rare to non-existant,\n especially on such embedded setups.\n\n 2. Many huge activation batches. Those batches only occur when the\n working set fluctuates. If it changes completely between every full\n LRU cycle, you have problematic reclaim overhead anyway.\n\n 3. Access of activated pages at maximum speed: sequential loads from\n every single page without doing anything in between. In reality,\n the extra faults will get distributed between actual operations on\n the data.\n\nSo even if a workload manages to get the VM into the situation of\nactivating a third of memory in one go on such a setup, it will take\n2.2 seconds instead 2.1 without the patch.\n\nComparing the numbers (and my user-experience over several months),\nI think this change is an overall improvement to the VM.\n\nPatch 1 is only refactoring to break up that ugly compound conditional\nin shrink_page_list() and make it easy to document and add new checks\nin a readable fashion.\n\nPatch 2 gets rid of the obsolete page_mapping_inuse(). It\u0027s not\nstrictly related to #3, but it was in the original submission and is a\nnet simplification, so I kept it.\n\nPatch 3 implements used-once detection of mapped file pages.\n\nThis patch:\n\nMoving the big conditional into its own predicate function makes the code\na bit easier to read and allows for better commenting on the checks\none-by-one.\n\nThis is just cleaning up, no semantics should have been changed.\n\nSigned-off-by: Johannes Weiner \u003channes@cmpxchg.org\u003e\nReviewed-by: Rik van Riel \u003criel@redhat.com\u003e\nCc: Minchan Kim \u003cminchan.kim@gmail.com\u003e\nCc: OSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Lee Schermerhorn \u003clee.schermerhorn@hp.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "e7c84ee22b8321fa0130a53d4c9806474d62eff0", "tree": "b1cf4f6f9337af1764a0bad0af0e6bde75e573a5", "parents": [ "a1b57ac061b0e348c9a878f8fa3a93a67fe6af42" ], "author": { "name": "Mel Gorman", "email": "mel@csn.ul.ie", "time": "Fri Mar 05 13:42:16 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Mar 06 11:26:26 2010 -0800" }, "message": "mm: document /sys/devices/system/node/nodeX\n\nAdd a bare description of what /sys/devices/system/node/nodeX is.

Specifically, each anon_vma will be shared between the parent\nprocess and all its child processes.\n\nIn a workload with 1000 child processes and a VMA with 1000 anonymous\npages per process that get COWed, this leads to a system with a million\nanonymous pages in the same anon_vma, each of which is mapped in just one\nof the 1000 processes. However, the current rmap code needs to walk them\nall, leading to O(N) scanning complexity for each page.\n\nThis can result in systems where one CPU is walking the page tables of\n1000 processes in page_referenced_one, while all other CPUs are stuck on\nthe anon_vma lock. This leads to catastrophic failure for a benchmark\nlike AIM7, where the total number of processes can reach in the tens of\nthousands. Real workloads are still a factor 10 less process intensive\nthan AIM7, but they are catching up.\n\nThis patch changes the way anon_vmas and VMAs are linked, which allows us\nto associate multiple anon_vmas with a VMA. At fork time, each child\nprocess gets its own anon_vmas, in which its COWed pages will be\ninstantiated. The parents\u0027 anon_vma is also linked to the VMA, because\nnon-COWed pages could be present in any of the children.\n\nThis reduces rmap scanning complexity to O(1) for the pages of the 1000\nchild processes, with O(N) complexity for at most 1/N pages in the system.\n This reduces the average scanning cost in heavily forking workloads from\nO(N) to 2.\n\nThe only real complexity in this patch stems from the fact that linking a\nVMA to anon_vmas now involves memory allocations. This means vma_adjust\ncan fail, if it needs to attach a VMA to anon_vma structures. This in\nturn means error handling needs to be added to the calling functions.\n\nA second source of complexity is that, because there can be multiple\nanon_vmas, the anon_vma linking in vma_adjust can no longer be done under\n\"the\" anon_vma lock. To prevent the rmap code from walking up an\nincomplete VMA, this patch introduces the VM_LOCK_RMAP VMA flag. This bit\nflag uses the same slot as the NOMMU VM_MAPPED_COPY, with an ifdef in mm.h\nto make sure it is impossible to compile a kernel that needs both symbolic\nvalues for the same bitflag.\n\nSome test results:\n\nWithout the anon_vma changes, when AIM7 hits around 9.7k users (on a test\nbox with 16GB RAM and not quite enough IO), the system ends up running\n\u003e99% in system time, with every CPU on the same anon_vma lock in the\npageout code.\n\nWith these changes, AIM7 hits the cross-over point around 29.7k users.\nThis happens with ~99% IO wait time, there never seems to be any spike in\nsystem time. The anon_vma lock contention appears to be resolved.\n\n[akpm@linux-foundation.org: cleanups]\nSigned-off-by: Rik van Riel \u003criel@redhat.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Larry Woodman \u003clwoodman@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\nCc: Minchan Kim \u003cminchan.kim@gmail.com\u003e\nCc: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nCc: Hugh Dickins \u003chugh.dickins@tiscali.co.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "648bcc771145172a14bc35eeb849ed08f6aa4f1e", "tree": "3cc7da55d1ca18b46cb0518b3b35c276adc0aad1", "parents": [ "19adf9c5d5793657118f2002237c0ee49c3b6185" ], "author": { "name": "Thiago Farina", "email": "tfransosi@gmail.com", "time": "Fri Mar 05 13:42:04 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Mar 06 11:26:26 2010 -0800" }, "message": "mm/memcontrol.c: fix \"integer as NULL pointer\" sparse warning\n\nmm/memcontrol.c:2548:32: warning: Using plain integer as NULL pointer\n\nSigned-off-by: Thiago Farina \u003ctfransosi@gmail.com\u003e\nAcked-by: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "19adf9c5d5793657118f2002237c0ee49c3b6185", "tree": "ed5d2bdb437253486cb803799e2f4e26e27277e6", "parents": [ "0141450f66c3c12a3aaa869748caa64241885cdf" ], "author": { "name": "Andrew Morton", "email": "akpm@linux-foundation.org", "time": "Fri Mar 05 13:42:03 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Mar 06 11:26:25 2010 -0800" }, "message": "include/linux/fs.h: convert FMODE_* constants to hex\n\nIt was tolerable until Eric went and added 8388608.\n\nCc: Eric Paris \u003ceparis@redhat.com\u003e\nCc: Wu Fengguang \u003cfengguang.wu@intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "0141450f66c3c12a3aaa869748caa64241885cdf", "tree": "cab5f621dafd1f133d915e5c60aea160438a2e11", "parents": [ "42e49608683ab25fbbbf9c40edb944601e543882" ], "author": { "name": "Wu Fengguang", "email": "fengguang.wu@intel.com", "time": "Fri Mar 05 13:42:03 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Mar 06 11:26:25 2010 -0800" }, "message": "readahead: introduce FMODE_RANDOM for POSIX_FADV_RANDOM\n\nThis fixes inefficient page-by-page reads on POSIX_FADV_RANDOM.\n\nPOSIX_FADV_RANDOM used to set ra_pages\u003d0, which leads to poor performance:\na 16K read will be carried out in 4 _sync_ 1-page reads.\n\nIn other places, ra_pages\u003d\u003d0 means\n- it\u0027s ramfs/tmpfs/hugetlbfs/sysfs/configfs\n- some IO error happened\nwhere multi-page read IO won\u0027t help or should be avoided.\n\nPOSIX_FADV_RANDOM actually want a different semantics: to disable the\n*heuristic* readahead algorithm, and to use a dumb one which faithfully\nsubmit read IO for whatever application requests.\n\nSo introduce a flag FMODE_RANDOM for POSIX_FADV_RANDOM.\n\nNote that the random hint is not likely to help random reads performance\nnoticeably.
