If a task were to be killed while attached to an mm that could not be\nfreed because another thread were set to OOM_DISABLE, it would have\nneedlessly been terminated since there is no potential for future memory\nfreeing.\n\nThis patch moves oomkilladj (now more appropriately named oom_adj) from\nstruct task_struct to struct mm_struct. This requires task_lock() on a\ntask to check its oom_adj value to protect against exec, but it\u0027s already\nnecessary to take the lock when dereferencing the mm to find the total VM\nsize for the badness heuristic.\n\nThis fixes a livelock if the oom killer chooses a task and another thread\nsharing the same memory has an oom_adj value of OOM_DISABLE. This occurs\nbecause oom_kill_task() repeatedly returns 1 and refuses to kill the\nchosen task while select_bad_process() will repeatedly choose the same\ntask during the next retry.\n\nTaking task_lock() in select_bad_process() to check for OOM_DISABLE and in\noom_kill_task() to check for threads sharing the same memory will be\nremoved in the next patch in this series where it will no longer be\nnecessary.\n\nWriting to /proc/pid/oom_adj for a kthread will now return -EINVAL since\nthese threads are immune from oom killing already. They simply report an\noom_adj value of OOM_DISABLE.\n\nCc: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nSigned-off-by: David Rientjes \u003crientjes@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "6837765963f1723e80ca97b1fae660f3a60d77df", "tree": "a9a6ed4b7e3bf188966da78b04bf39298f24375a", "parents": [ "bce7394a3ef82b8477952fbab838e4a6e8cb47d2" ], "author": { "name": "KOSAKI Motohiro", "email": "kosaki.motohiro@jp.fujitsu.com", "time": "Tue Jun 16 15:32:51 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jun 16 19:47:42 2009 -0700" }, "message": "mm: remove CONFIG_UNEVICTABLE_LRU config option\n\nCurrently, nobody wants to turn UNEVICTABLE_LRU off.

This solves two problems:\n\n (1) In SYSV SHM where nattch for a segment does not reflect the number of\n shmat\u0027s (and forks) done.\n\n (2) In mmap() where the VMA\u0027s vm_mm is set to point to the parent mm by an\n exec\u0027ing process when VM_EXECUTABLE is specified, regardless of the fact\n that a VMA might be shared and already have its vm_mm assigned to another\n process or a dead process.\n\nA new struct (vm_region) is introduced to track a mapped region and to remember\nthe circumstances under which it may be shared and the vm_list_struct structure\nis discarded as it\u0027s no longer required.\n\nThis patch makes the following additional changes:\n\n (1) Regions are now allocated with alloc_pages() rather than kmalloc() and\n with no recourse to __GFP_COMP, so the pages are not composite. Instead,\n each page has a reference on it held by the region. Anything else that is\n interested in such a page will have to get a reference on it to retain it.\n When the pages are released due to unmapping, each page is passed to\n put_page() and will be freed when the page usage count reaches zero.\n\n (2) Excess pages are trimmed after an allocation as the allocation must be\n made as a power-of-2 quantity of pages.\n\n (3) VMAs are added to the parent MM\u0027s R/B tree and mmap lists. As an MM may\n end up with overlapping VMAs within the tree, the VMA struct address is\n appended to the sort key.\n\n (4) Non-anonymous VMAs are now added to the backing inode\u0027s prio list.\n\n (5) Holes may be punched in anonymous VMAs with munmap(), releasing parts of\n the backing region. The VMA and region structs will be split if\n necessary.\n\n (6) sys_shmdt() only releases one attachment to a SYSV IPC shared memory\n segment instead of all the attachments at that addresss. Multiple\n shmat()\u0027s return the same address under NOMMU-mode instead of different\n virtual addresses as under MMU-mode.\n\n (7) Core dumping for ELF-FDPIC requires fewer exceptions for NOMMU-mode.\n\n (8) /proc/maps is now the global list of mapped regions, and may list bits\n that aren\u0027t actually mapped anywhere.\n\n (9) /proc/meminfo gains a line (tagged \"MmapCopy\") that indicates the amount\n of RAM currently allocated by mmap to hold mappable regions that can\u0027t be\n mapped directly. These are copies of the backing device or file if not\n anonymous.\n\nThese changes make NOMMU mode more similar to MMU mode. The downside is that\nNOMMU mode requires some extra memory to track things over NOMMU without this\npatch (VMAs are no longer shared, and there are now region structs).\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nTested-by: Mike Frysinger \u003cvapier.adi@gmail.com\u003e\nAcked-by: Paul Mundt \u003clethal@linux-sh.org\u003e\n" }, { "commit": "a0c9f240a992c4c2b6ac40324ece27475cf3b71a", "tree": "e42e5231d0e551b1b1f726c06c2ca27c510efb7a", "parents": [ "5bb47b9ff3d16d40f8d45380b373497a545fa280", "230e40fbda242544389a5428a2efac568178ddfe" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Jan 07 12:01:06 2009 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Jan 07 12:01:06 2009 -0800" }, "message": "Merge branch \u0027proc-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/adobriyan/proc\n\n* \u0027proc-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/adobriyan/proc:\n proc: remove write-only variable in proc_pident_lookup()\n proc: fix sparse warning\n proc: add /proc/*/stack\n proc: remove \u0027##\u0027 usage\n proc: remove useless WARN_ONs\n proc: stop using BKL\n" }, { "commit": "57c44c5f6fb0a8002feb258c1af58e1a744b1fcb", "tree": "978bd46ca765a88e9c101cb705bbb0bf46015643", "parents": [ "76052749143d03006271cc0ce8205ad756917062", "5a9e67b1a19e08a82387709f325d26e07b891d27" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Jan 07 11:31:52 2009 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Jan 07 11:31:52 2009 -0800" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/trivial\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/trivial: (24 commits)\n trivial: chack -\u003e check typo fix in main Makefile\n trivial: Add a space (and a comma) to a printk in 8250 driver\n trivial: Fix misspelling of \"firmware\" in docs for ncr53c8xx/sym53c8xx\n trivial: Fix misspelling of \"firmware\" in powerpc Makefile\n trivial: Fix misspelling of \"firmware\" in usb.c\n trivial: Fix misspelling of \"firmware\" in qla1280.c\n trivial: Fix misspelling of \"firmware\" in a100u2w.c\n trivial: Fix misspelling of \"firmware\" in megaraid.c\n trivial: Fix misspelling of \"firmware\" in ql4_mbx.c\n trivial: Fix misspelling of \"firmware\" in acpi_memhotplug.c\n trivial: Fix misspelling of \"firmware\" in ipw2100.c\n trivial: Fix misspelling of \"firmware\" in atmel.c\n trivial: Fix misspelled firmware in Kconfig\n trivial: fix an -\u003e a typos in documentation and comments\n trivial: fix then -\u003e than typos in comments and documentation\n trivial: update Jesper Juhl CREDITS entry with new email\n trivial: fix singal -\u003e signal typo\n trivial: Fix incorrect use of \"loose\" in event.c\n trivial: printk: fix indentation of new_text_line declaration\n trivial: rtc-stk17ta8: fix sparse warning\n ...\n" }, { "commit": "3340289ddf29ca75c3acfb3a6b72f234b2f74d5c", "tree": "d5da94eb1cb0146160fcb0e7aa161bfa5b6ac807", "parents": [ "08fba69986e20c1c9e5fe2e6064d146cc4f42480" ], "author": { "name": "Mel Gorman", "email": "mel@csn.ul.ie", "time": "Tue Jan 06 14:38:54 2009 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jan 06 15:58:58 2009 -0800" }, "message": "mm: report the MMU pagesize in /proc/pid/smaps\n\nThe KernelPageSize entry in /proc/pid/smaps is the pagesize used by the\nkernel to back a VMA.
