It is known that hiearchies are\nexpensive, so the user needs to be careful and aware of the trade-offs\nbefore creating very deep ones.\n\n[akpm@linux-foundation.org: coding-style fixes]\nSigned-off-by: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\nCc: YAMAMOTO Takashi \u003cyamamoto@valinux.co.jp\u003e\nCc: Paul Menage \u003cmenage@google.com\u003e\nCc: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Pavel Emelianov \u003cxemul@openvz.org\u003e\nCc: Dhaval Giani \u003cdhaval@linux.vnet.ibm.com\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "a47295e6bc42ad35f9c15ac66f598aa24debd4e2", "tree": "cb765e996ef35ae88e29d60796655d0d35e8cf5e", "parents": [ "e7b80bb695a5b64c92e314838e083b2f3bdf29b2" ], "author": { "name": "Paul Menage", "email": "menage@google.com", "time": "Wed Jan 07 18:07:44 2009 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jan 08 08:31:03 2009 -0800" }, "message": "cgroups: make cgroup_path() RCU-safe\n\nFix races between /proc/sched_debug by freeing cgroup objects via an RCU\ncallback.

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": "8cfc7f9c005313ecd4e98ad1feb391d8dfce9ed2", "tree": "39a3a898f5a15f3c190e7b1a09815f13bbaef77c", "parents": [ "b424e8d3b438e841cd1700f6433a100a5d611e4a", "da8d5089da6dfd54e5fd05d0c291a63c2bcf6885" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Jan 07 15:43:58 2009 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Jan 07 15:43:58 2009 -0800" }, "message": "Merge branch \u0027sched-fixes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip\n\n* \u0027sched-fixes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:\n sched: fix possible recursive rq-\u003elock\n" }, { "commit": "b424e8d3b438e841cd1700f6433a100a5d611e4a", "tree": "545638d0b925de4c7f740286760767cca86cb91e", "parents": [ "7c7758f99d39d529a64d4f60d22129bbf2f16d74", "f6dc1e5e3d4b523e1616b43beddb04e4fb1d376a" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Jan 07 15:41:01 2009 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Jan 07 15:41:01 2009 -0800" }, "message": "Merge branch \u0027linux-next\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6\n\n* \u0027linux-next\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6: (98 commits)\n PCI PM: Put PM callbacks in the order of execution\n PCI PM: Run default PM callbacks for all devices using new framework\n PCI PM: Register power state of devices during initialization\n PCI PM: Call pci_fixup_device from legacy routines\n PCI PM: Rearrange code in pci-driver.c\n PCI PM: Avoid touching devices behind bridges in unknown state\n PCI PM: Move pci_has_legacy_pm_support\n PCI PM: Power-manage devices without drivers during suspend-resume\n PCI PM: Add suspend counterpart of pci_reenable_device\n PCI PM: Fix poweroff and restore callbacks\n PCI: Use msleep instead of cpu_relax during ASPM link retraining\n PCI: PCIe portdrv: Add kerneldoc comments to remining core funtions\n PCI: PCIe portdrv: Rearrange code so that related things are together\n PCI: PCIe portdrv: Fix suspend and resume of PCI Express port services\n PCI: PCIe portdrv: Add kerneldoc comments to some core functions\n x86/PCI: Do not use interrupt links for devices using MSI-X\n net: sfc: Use pci_clear_master() to disable bus mastering\n PCI: Add pci_clear_master() as opposite of pci_set_master()\n PCI hotplug: remove redundant test in cpq hotplug\n PCI: pciehp: cleanup register and field definitions\n ...\n" }, { "commit": "67acd8b4b7a3f1b183ae358e1dfdb8a80e170736", "tree": "4418034f6e83f954337a17bc6a872fa5ae3c4b5e", "parents": [ "b13d3720ecd29d5044334fdbbae3432f26802bae", "ad160d23198193135cb2bcc75222e0816b5838c0" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Jan 07 15:35:47 2009 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Jan 07 15:35:47 2009 -0800" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/arjan/linux-2.6-async\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/arjan/linux-2.6-async:\n async: don\u0027t do the initcall stuff post boot\n bootchart: improve output based on Dave Jones\u0027 feedback\n async: make the final inode deletion an asynchronous event\n fastboot: Make libata initialization even more async\n fastboot: make the libata port scan asynchronous\n fastboot: make scsi probes asynchronous\n async: Asynchronous function calls to speed up kernel boot\n" }, { "commit": "c9d557c19f94df42db78d4a5de4d25feee694bad", "tree": "a52f75630be16e6abf0cc11b70c089fa49905453", "parents": [ "8903709b054a8dafe4e8c6d9a6444034d7aba36f" ], "author": { "name": "Paul E.

pci_request_regions() (and similar APIs) have a\nreasonable expectation that they are the only ones accessing their device.\nAs part of the e1000e hunt, we were afraid that some userland (X or some\nbootsplash stuff) was mapping the MMIO region that the driver thought it\nhad exclusively via /dev/mem or via various sysfs resource mappings.\n\nThis patch adds the option for device drivers to cause their reserved\nregions to the \"banned from /dev/mem use\" list, so now both kernel memory\nand device-exclusive MMIO regions are banned.\nNOTE: This is only active when CONFIG_STRICT_DEVMEM is set.\n\nIn addition to the config option, a kernel parameter iomem\u003drelaxed is\nprovided for the cases where developers want to diagnose, in the field,\ndrivers issues from userspace.\n\nReviewed-by: Matthew Wilcox \u003cwilly@linux.intel.com\u003e\nSigned-off-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nSigned-off-by: Jesse Barnes
