As a band-aid, kernel.h\n was including \u003casm/bug.h\u003e to pseudo link them.\n\n This has caused confusion[1] and general yuck/WTF[2] reactions.

There are already a number of filter flags in\n/proc/\u003cpid\u003e/coredump_filter, however, these allow one to specify \u0027types\u0027\nof kernel memory, not specific address ranges (which is needed in this\ncase).\n\nSince there are no more vma flags available, the first patch eliminates\nthe need for the \u0027VM_ALWAYSDUMP\u0027 flag. The flag is used internally by\nthe kernel to mark vdso and vsyscall pages. However, it is simple\nenough to check if a vma covers a vdso or vsyscall page without the need\nfor this flag.\n\nThe second patch then replaces the \u0027VM_ALWAYSDUMP\u0027 flag with a new\n\u0027VM_NODUMP\u0027 flag, which can be set by userspace using new madvise flags:\n\u0027MADV_DONTDUMP\u0027, and unset via \u0027MADV_DODUMP\u0027. The core dump filters\ncontinue to work the same as before unless \u0027MADV_DONTDUMP\u0027 is set on the\nregion.\n\nThe qemu code which implements this features is at:\n\n http://people.redhat.com/~jbaron/qemu-dump/qemu-dump.patch\n\nIn my testing the qemu core dump shrunk from 383MB -\u003e 13MB with this\npatch.\n\nI also believe that the \u0027MADV_DONTDUMP\u0027 flag might be useful for\nsecurity sensitive apps, which might want to select which areas are\ndumped.\n\nThis patch:\n\nThe VM_ALWAYSDUMP flag is currently used by the coredump code to\nindicate that a vma is part of a vsyscall or vdso section. However, we\ncan determine if a vma is in one these sections by checking it against\nthe gate_vma and checking for a non-NULL return value from\narch_vma_name().

An example\nis when a driver needs to start a DMA engine if the caller polls for\nPOLLIN, but doesn\u0027t want to do that if POLLIN is not requested but instead\nonly POLLOUT or POLLPRI is requested. This is something that can happen\nin the video4linux subsystem among others.\n\nUnfortunately, the current epoll/poll/select implementation doesn\u0027t\nprovide that information reliably. The poll_table_struct does have it: it\nhas a key field with the event mask. But once a poll() call matches one\nor more bits of that mask any following poll() calls are passed a NULL\npoll_table pointer.\n\nAlso, the eventpoll implementation always left the key field at ~0 instead\nof using the requested events mask.\n\nThis was changed in eventpoll.c so the key field now contains the actual\nevents that should be polled for as set by the caller.\n\nThe solution to the NULL poll_table pointer is to set the qproc field to\nNULL in poll_table once poll() matches the events, not the poll_table\npointer itself. That way drivers can obtain the mask through a new\npoll_requested_events inline.\n\nThe poll_table_struct can still be NULL since some kernel code calls it\ninternally (netfs_state_poll() in ./drivers/staging/pohmelfs/netfs.h). In\nthat case poll_requested_events() returns ~0 (i.e. all events).\n\nVery rarely drivers might want to know whether poll_wait will actually\nwait. If another earlier file descriptor in the set already matched the\nevents the caller wanted to wait for, then the kernel will return from the\nselect() call without waiting. This might be useful information in order\nto avoid doing expensive work.\n\nA new helper function poll_does_not_wait() is added that drivers can use\nto detect this situation. This is now used in sock_poll_wait() in\ninclude/net/sock.h. This was the only place in the kernel that needed\nthis information.\n\nDrivers should no longer access any of the poll_table internals, but use\nthe poll_requested_events() and poll_does_not_wait() access functions\ninstead. In order to enforce that the poll_table fields are now prepended\nwith an underscore and a comment was added warning against using them\ndirectly.\n\nThis required a change in unix_dgram_poll() in unix/af_unix.c which used\nthe key field to get the requested events. It\u0027s been replaced by a call\nto poll_requested_events().\n\nFor qproc it was especially important to change its name since the\nbehavior of that field changes with this patch since this function pointer\ncan now be NULL when that wasn\u0027t possible in the past.\n\nAny driver accessing the qproc or key fields directly will now fail to compile.\n\nSome notes regarding the correctness of this patch: the driver\u0027s poll()\nfunction is called with a \u0027struct poll_table_struct *wait\u0027 argument. This\npointer may or may not be NULL, drivers can never rely on it being one or\nthe other as that depends on whether or not an earlier file descriptor in\nthe select()\u0027s fdset matched the requested events.\n\nThere are only three things a driver can do with the wait argument:\n\n1) obtain the key field:\n\n\tevents \u003d wait ? wait-\u003ekey : ~0;\n\n This will still work although it should be replaced with the new\n poll_requested_events() function (which does exactly the same).\n This will now even work better, since wait is no longer set to NULL\n unnecessarily.\n\n2) use the qproc callback. This could be deadly since qproc can now be\n NULL. Renaming qproc should prevent this from happening. There are no\n kernel drivers that actually access this callback directly, BTW.\n\n3) test whether wait \u003d\u003d NULL to determine whether poll would return without\n waiting. This is no longer sufficient as the correct test is now\n wait \u003d\u003d NULL || wait-\u003e_qproc \u003d\u003d NULL.\n\n However, the worst that can happen here is a slight performance hit in\n the case where wait !\u003d NULL and wait-\u003e_qproc \u003d\u003d NULL. In that case the\n driver will assume that poll_wait() will actually add the fd to the set\n of waiting file descriptors. Of course, poll_wait() will not do that\n since it tests for wait-\u003e_qproc. This will not break anything, though.\n\n There is only one place in the whole kernel where this happens\n (sock_poll_wait() in include/net/sock.h) and that code will be replaced\n by a call to poll_does_not_wait() in the next patch.\n\n Note that even if wait-\u003e_qproc !\u003d NULL drivers cannot rely on poll_wait()\n actually waiting. The next file descriptor from the set might match the\n event mask and thus any possible waits will never happen.\n\nSigned-off-by: Hans Verkuil \u003chans.verkuil@cisco.com\u003e\nReviewed-by: Jonathan Corbet \u003ccorbet@lwn.net\u003e\nReviewed-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Davide Libenzi \u003cdavidel@xmailserver.org\u003e\nSigned-off-by: Hans de Goede \u003chdegoede@redhat.com\u003e\nCc: Mauro Carvalho Chehab \u003cmchehab@infradead.org\u003e\nCc: David Miller \u003cdavem@davemloft.net\u003e\nCc: Eric Dumazet \u003ceric.dumazet@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": "46c5801eaf86e83cb3a4142ad35188db5011fff0", "tree": "2b8a8f7709aa7dadafdf13f823488cf51e2e2fed", "parents": [ "78dff4189708d07cdcaf7bfd1b04ebe78ac9c041" ], "author": { "name": "Darrick J.

Many services daemonize by double-forking and get implicitly\nre-parented to PID 1. The service manager will no longer be able to\nreceive the SIGCHLD signals for them, and is no longer in charge of\nreaping the children with wait(). All information about the children is\nlost at the moment PID 1 cleans up the re-parented processes.\n\nWith this prctl, a service manager process can mark itself as a sort of\n\u0027sub-init\u0027, able to stay as the parent for all orphaned processes\ncreated by the started services. All SIGCHLD signals will be delivered\nto the service manager.\n\nReceiving SIGCHLD and doing wait() is in cases of a service-manager much\npreferred over any possible asynchronous notification about specific\nPIDs, because the service manager has full access to the child process\ndata in /proc and the PID can not be re-used until the wait(), the\nservice-manager itself is in charge of, has happened.\n\nAs a side effect, the relevant parent PID information does not get lost\nby a double-fork, which results in a more elaborate process tree and\n\u0027ps\u0027 output:\n\nbefore:\n # ps afx\n 253 ?

The changes are\n well contained and just plug into the driver new gpu functionality\n so they should be fairly regression proof. I just want to give\n them a bit of a run on the hw AMD kindly sent me.\n\n b) drm prime/dma-buf interface code. This is just infrastructure\n code to expose the dma-buf stuff to drm drivers and to userspace.\n I\u0027m not planning on pushing any driver support in this cycle\n (except maybe exynos), but I\u0027d like to get the infrastructure code\n in so for the next cycle I can start getting the driver support\n into the individual drivers. We have started driver support for\n i915, nouveau and udl along with I think exynos and omap in\n staging. However this code relies on the dma-buf tree being\n pulled into your tree first since it needs the latest interfaces\n from that tree. I\u0027ll push to get that tree sent asap.\n\n (oh and any warnings you see in i915 are gcc\u0027s fault from what anyone\n can see).\"\n\nFix up trivial conflicts in arch/x86/platform/mrst/mrst.c due to the new\nmsic_thermal_platform_data() thermal function being added next to the\ntc35876x_platform_data() i2c device function..\n\n* \u0027drm-next\u0027 of git://people.freedesktop.org/~airlied/linux: (326 commits)\n drm/i915: use DDC_ADDR instead of hard-coding it\n drm/radeon: use DDC_ADDR instead of hard-coding it\n drm: remove unneeded redefinition of DDC_ADDR\n drm/exynos: added virtual display driver.\n drm: allow loading an EDID as firmware to override broken monitor\n drm/exynos: enable hdmi audio feature\n drm/exynos: add default pixel format for plane\n drm/exynos: cleanup exynos_hdmi.h\n drm/exynos: add is_local member in exynos_drm_subdrv struct\n drm/exynos: add subdrv open/close functions\n drm/exynos: remove module of exynos drm subdrv\n drm/exynos: release pending pageflip events when closed\n drm/exynos: added new funtion to get/put dma address.\n drm/exynos: update gem and buffer framework.\n drm/exynos: added mode_fixup feature and code clean.\n drm/exynos: add HDMI version 1.4 support\n drm/exynos: remove exynos_mixer.h\n gma500: Fix mmap frambuffer\n drm/radeon: Drop radeon_gem_object_(un)pin.\n drm/radeon: Restrict offset for legacy display engine.\n ...\n" }, { "commit": "b2094ef840697bc8ca5d17a83b7e30fad5f1e9fa", "tree": "64e5f7253b6a85b6d5d36f95c0d3c67c1798918d", "parents": [ "424a6f6ef990b7e9f56f6627bfc6c46b493faeb4", "6681bc0deba495fad0d6fb349e40524abd1b1732" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Mar 22 13:00:13 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Mar 22 13:00:13 2012 -0700" }, "message": "Merge tag \u0027sound-3.4\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound\n\nPull updates of sound stuff from Takashi Iwai:\n \"Here is the first big update chunk of sound stuff for 3.4-rc1.\n\n In the common sound infrastructure, there are a few changes for\n dynamic PCM support (used in ASoC) and a few clean-ups. Majority of\n changes are found, as usual, in HD-audio and ASoC.\n\n Some highlights of HD-audio changes:\n\n - All the long-standing static quirk codes for Realtek codec were\n finally removed by fixing and extending the Realtek auto-parser.\n\n - The mute-LED control is standardized over all HD-audio codec\n drivers using the extended vmaster hook.\n\n - The vmaster slave mixer elements are initialized to 0dB as default\n so that the user won\u0027t be annoyed by the silent output after\n updates, e.g. due to the additions of new elements.\n\n - Other many fix-ups for the misc HD-audio devices.\n\n In the ASoC side, this is a very active release, including a quite a\n few framework enhancements. Some highlights:\n\n - Support for widgets not associated with a CODEC, an important part\n of the dynamic PCM framework.\n\n - A library factoring out the common code shared by dmaengine based\n DMA drivers contributed by Lars-Peter Clausen. This will save a\n lot of code and make it much easier to deploy enhancements to\n dmaengine.\n\n - Support for binary controls, used for providing runtime\n configuration of algorithm coefficients.\n\n - A new DAPM widget type for regulator supplies allowing drivers for\n devices that can power down unused supplies while active to do\n without any per-driver code.\n\n - DAPM widgets for DAIs, initially giving a speed boost for playback\n startup and shutdown and also the basis for CODEC\u003c-\u003eCODEC DAI link\n support.\n\n - Support for specifying the number of significant bits on audio\n interfaces, useful for allowing applications to know how much\n effort to put into generating data for a larger sample format.\n\n - Conversion of the FSI driver used on some SH processors to\n DMAEngine.\n\n - Conversion of EP93xx drivers to DMAEngine.\n\n - New CODEC drivers for Maxim MAX9768 and Wolfson Microelectronics\n WM2200.\n\n - Move audmux driver from arc/arm to sound/soc\n\n - McBSP move from arch/ to sound/ and updates\n\n Also, a few small updates and fixes for other drivers like au88x0,\n ymfpci, USB 6fire, USB usx2yaudio are included.\"\n\n* tag \u0027sound-3.4\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (446 commits)\n ASoC: wm8994: Provide VMID mode control and fix default sequence\n ASoC: wm8994: Add missing break in resume\n ASoC: wm_hubs: Don\u0027t actively manage LINEOUT_VMID_BUF\n ASoC: pxa-ssp: atomically set stream active masks\n ASoC: fsl: p1022ds: tell the WM8776 codec driver that it\u0027s the master\n ASoC: Samsung: Added to support mono recording\n ALSA: hda - Fix build with CONFIG_PM\u003dn\n ALSA: au88x0 - Avoid possible Oops at unbinding\n ALSA: usb-audio - Fix build error by consitification of rate list\n ASoC: core: Fix obscure leak of runtime array\n ALSA: pcm - Avoid GFP_ATOMIC in snd_pcm_link()\n ALSA: pcm: Constify the list in snd_pcm_hw_constraint_list\n ASoC: wm8996: Add 44.1kHz support\n ALSA: hda - Fix build of patch_sigmatel.c without CONFIG_SND_HDA_POWER_SAVE\n ASoC: mx27vis-aic32x4: Convert it to platform driver\n ALSA: hda - fix printing of high HDMI sample rates\n ALSA: ymfpci - Fix legacy registers on S3/S4 resume\n ALSA: control - Fixe a trailing white space error\n ALSA: hda - Add expose_enum_ctl flag to snd_hda_add_vmaster_hook()\n ALSA: hda - Add \"Mute-LED Mode\" enum control\n ...\n" }, { "commit": "424a6f6ef990b7e9f56f6627bfc6c46b493faeb4", "tree": "0028356ed8003495fbbe1f716f359e3c8ebc35b6", "parents": [ "1ab142d499294b844ecc81e8004db4ce029b0b61", "cd8df932d894f3128c884e3ae1b2b484540513db" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Mar 22 12:55:29 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Mar 22 12:55:29 2012 -0700" }, "message": "Merge tag \u0027scsi-misc\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6\n\nSCSI updates from James Bottomley:\n \"The update includes the usual assortment of driver updates (lpfc,\n qla2xxx, qla4xxx, bfa, bnx2fc, bnx2i, isci, fcoe, hpsa) plus a huge\n amount of infrastructure work in the SAS library and transport class\n as well as an iSCSI update.

It is going to be a\n bit more nasty than usual as in touching things outside of\n arch/powerpc mostly due to the big iSeriesectomy :-) We finally got\n rid of the bugger (legacy iSeries support) which was a PITA to\n maintain and that nobody really used anymore.\n\n Here are some of the highlights:\n\n - Legacy iSeries is gone. Thanks Stephen ! There\u0027s still some bits\n and pieces remaining if you do a grep -ir series arch/powerpc but\n they are harmless and will be removed in the next few weeks\n hopefully.\n\n - The \u0027fadump\u0027 functionality (Firmware Assisted Dump) replaces the\n previous (equivalent) \"pHyp assisted dump\"... it\u0027s a rewrite of a\n mechanism to get the hypervisor to do crash dumps on pSeries, the\n new implementation hopefully being much more reliable. Thanks\n Mahesh Salgaonkar.\n\n - The \"EEH\" code (pSeries PCI error handling \u0026 recovery) got a big\n spring cleaning, motivated by the need to be able to implement a\n new backend for it on top of some new different type of firwmare.\n\n The work isn\u0027t complete yet, but a good chunk of the cleanups is\n there. Note that this adds a field to struct device_node which is\n not very nice and which Grant objects to. I will have a patch soon\n that moves that to a powerpc private data structure (hopefully\n before rc1) and we\u0027ll improve things further later on (hopefully\n getting rid of the need for that pointer completely). Thanks Gavin\n Shan.\n\n - I dug into our exception \u0026 interrupt handling code to improve the\n way we do lazy interrupt handling (and make it work properly with\n \"edge\" triggered interrupt sources), and while at it found \u0026 fixed\n a wagon of issues in those areas, including adding support for page\n fault retry \u0026 fatal signals on page faults.\n\n - Your usual random batch of small fixes \u0026 updates, including a bunch\n of new embedded boards, both Freescale and APM based ones, etc...\"\n\nI fixed up some conflicts with the generalized irq-domain changes from\nGrant Likely, hopefully correctly.\n\n* \u0027next\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: (141 commits)\n powerpc/ps3: Do not adjust the wrapper load address\n powerpc: Remove the rest of the legacy iSeries include files\n powerpc: Remove the remaining CONFIG_PPC_ISERIES pieces\n init: Remove CONFIG_PPC_ISERIES\n powerpc: Remove FW_FEATURE ISERIES from arch code\n tty/hvc_vio: FW_FEATURE_ISERIES is no longer selectable\n powerpc/spufs: Fix double unlocks\n powerpc/5200: convert mpc5200 to use of_platform_populate()\n powerpc/mpc5200: add options to mpc5200_defconfig\n powerpc/mpc52xx: add a4m072 board support\n powerpc/mpc5200: update mpc5200_defconfig to fit for charon board\n Documentation/powerpc/mpc52xx.txt: Checkpatch cleanup\n powerpc/44x: Add additional device support for APM821xx SoC and Bluestone board\n powerpc/44x: Add support PCI-E for APM821xx SoC and Bluestone board\n MAINTAINERS: Update PowerPC 4xx tree\n powerpc/44x: The bug fixed support for APM821xx SoC and Bluestone board\n powerpc: document the FSL MPIC message register binding\n powerpc: add support for MPIC message register API\n powerpc/fsl: Added aliased MSIIR register address to MSI node in dts\n powerpc/85xx: mpc8548cds - add 36-bit dts\n ...\n" }, { "commit": "ad12ab259d9131a53aa11c7c4561d97f7cc900df", "tree": "457e99e4c4b1facf029a6a094428eaef73f5d261", "parents": [ "30d73f375238441d6dc31de0d90bc39f5bb0bfe5", "220cca2a4f5867db595135e0450381032eb54902" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Mar 21 18:00:03 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Mar 21 18:00:03 2012 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-nmw\n\nPull gfs2 changes from Steven Whitehouse.\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-nmw:\n GFS2: Change truncate page allocation to be GFP_NOFS\n GFS2: call gfs2_write_alloc_required for each chunk\n GFS2: Clean up log flush header writing\n GFS2: Remove a __GFP_NOFAIL allocation\n GFS2: Flush pending glock work when evicting an inode\n GFS2: make sure rgrps are up to date in func gfs2_blk2rgrpd\n GFS2: Eliminate sd_rindex_mutex\n GFS2: Unlock rindex mutex on glock error\n GFS2: Make bd_cmp() static\n GFS2: Sort the ordered write list\n GFS2: FITRIM ioctl support\n GFS2: Move two functions from log.c to lops.c\n GFS2: glock statistics gathering\n" }, { "commit": "d8c37c480678ebe09bc570f33e085e28049db035", "tree": "c8c53fde803f1a9655f44193c97db76dc4a90fe1", "parents": [ "8d32ff84401f1addb961c7af2c8d9baceb0ab9ba" ], "author": { "name": "Naoya Horiguchi", "email": "n-horiguchi@ah.jp.nec.com", "time": "Wed Mar 21 16:34:27 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Mar 21 17:55:02 2012 -0700" }, "message": "thp: add HPAGE_PMD_* definitions for !CONFIG_TRANSPARENT_HUGEPAGE\n\nThese macros will be used in a later patch, where all usages are expected\nto be optimized away without #ifdef CONFIG_TRANSPARENT_HUGEPAGE.

The reason is that memcg has a\nfeature to move a page from a group to another group and we have race\nbetween \"move\" and \"page stat accounting\",\n\nUnder current logic, assume CPU-A and CPU-B. CPU-A does \"move\" and CPU-B\ndoes \"page stat accounting\".\n\nWhen CPU-A goes 1st,\n\n CPU-A CPU-B\n update \"struct page\" info.\n move_lock_mem_cgroup(memcg)\n see pc-\u003eflags\n copy page stat to new group\n overwrite pc-\u003emem_cgroup.\n move_unlock_mem_cgroup(memcg)\n move_lock_mem_cgroup(mem)\n set pc-\u003eflags\n update page stat accounting\n move_unlock_mem_cgroup(mem)\n\nstat accounting is guarded by move_lock_mem_cgroup() and \"move\" logic\n(CPU-A) doesn\u0027t see changes in \"struct page\" information.\n\nBut it\u0027s costly to have the same information both in \u0027struct page\u0027 and\n\u0027struct page_cgroup\u0027. And, there is a potential problem.\n\nFor example, assume we have PG_dirty accounting in memcg.\nPG_..is a flag for struct page.\nPCG_ is a flag for struct page_cgroup.\n(This is just an example. The same problem can be found in any\n kind of page stat accounting.)\n\n\t CPU-A CPU-B\n TestSet PG_dirty\n (delay) TestClear PG_dirty\n if (TestClear(PCG_dirty))\n memcg-\u003enr_dirty--\n if (TestSet(PCG_dirty))\n memcg-\u003enr_dirty++\n\nHere, memcg-\u003enr_dirty \u003d +1, this is wrong. This race was reported by Greg\nThelen \u003cgthelen@google.com\u003e. Now, only FILE_MAPPED is supported but\nfortunately, it\u0027s serialized by page table lock and this is not real bug,\n_now_,\n\nIf this potential problem is caused by having duplicated information in\nstruct page and struct page_cgroup, we may be able to fix this by using\noriginal \u0027struct page\u0027 information. But we\u0027ll have a problem in \"move\naccount\"\n\nAssume we use only PG_dirty.\n\n CPU-A CPU-B\n TestSet PG_dirty\n (delay) move_lock_mem_cgroup()\n if (PageDirty(page))\n new_memcg-\u003enr_dirty++\n pc-\u003emem_cgroup \u003d new_memcg;\n move_unlock_mem_cgroup()\n move_lock_mem_cgroup()\n memcg \u003d pc-\u003emem_cgroup\n new_memcg-\u003enr_dirty++\n\naccounting information may be double-counted. This was original reason to\nhave PCG_xxx flags but it seems PCG_xxx has another problem.\n\nI think we need a bigger lock as\n\n move_lock_mem_cgroup(page)\n TestSetPageDirty(page)\n update page stats (without any checks)\n move_unlock_mem_cgroup(page)\n\nThis fixes both of problems and we don\u0027t have to duplicate page flag into\npage_cgroup.

They don\u0027t interact with the\ngeneral quota handling code, and they don\u0027t much resemble its behaviour.\nRather than being about maintaining limits on on-disk block usage by\nparticular users, they are instead about maintaining limits on in-memory\npage usage (including anonymous MAP_PRIVATE copied-on-write pages)\nassociated with a particular hugetlbfs filesystem instance.\n\nWorse, they work by having callbacks to the hugetlbfs filesystem code from\nthe low-level page handling code, in particular from free_huge_page().\nThis is a layering violation of itself, but more importantly, if the\nkernel does a get_user_pages() on hugepages (which can happen from KVM\namongst others), then the free_huge_page() can be delayed until after the\nassociated inode has already been freed. If an unmount occurs at the\nwrong time, even the hugetlbfs superblock where the \"quota\" limits are\nstored may have been freed.\n\nAndrew Barry proposed a patch to fix this by having hugepages, instead of\nstoring a pointer to their address_space and reaching the superblock from\nthere, had the hugepages store pointers directly to the superblock,\nbumping the reference count as appropriate to avoid it being freed.\nAndrew Morton rejected that version, however, on the grounds that it made\nthe existing layering violation worse.\n\nThis is a reworked version of Andrew\u0027s patch, which removes the extra, and\nsome of the existing, layering violation. It works by introducing the\nconcept of a hugepage \"subpool\" at the lower hugepage mm layer - that is a\nfinite logical pool of hugepages to allocate from. hugetlbfs now creates\na subpool for each filesystem instance with a page limit set, and a\npointer to the subpool gets added to each allocated hugepage, instead of\nthe address_space pointer used now. The subpool has its own lifetime and\nis only freed once all pages in it _and_ all other references to it (i.e.\nsuperblocks) are gone.\n\nsubpools are optional - a NULL subpool pointer is taken by the code to\nmean that no subpool limits are in effect.\n\nPrevious discussion of this bug found in: \"Fix refcounting in hugetlbfs\nquota handling.\".

This is much cheaper on some architectures, including x86. The\nmain bulk of the patch is the retry logic if the nodemask changes in a\nmanner that can cause a false failure.\n\nWhile updating the nodemask, a check is made to see if a false failure\nis a risk.

The\nactual number of page faults is noticeably improved.\n\nFor benchmarks like kernel builds, the overall benefit is marginal but\nthe system CPU time is slightly reduced.\n\nTo test the actual bug the commit fixed I opened two terminals. The\nfirst ran within a cpuset and continually ran a small program that\nfaulted 100M of anonymous data. In a second window, the nodemask of the\ncpuset was continually randomised in a loop.\n\nWithout the commit, the program would fail every so often (usually\nwithin 10 seconds) and obviously with the commit everything worked fine.\nWith this patch applied, it also worked fine so the fix should be\nfunctionally equivalent.\n\nSigned-off-by: Mel Gorman \u003cmgorman@suse.de\u003e\nCc: Miao Xie \u003cmiaox@cn.fujitsu.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Christoph Lameter \u003ccl@linux.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "e845e199362cc5712ba0e7eedc14eed70e144258", "tree": "3968125d82e512c3aee44ed96694fdd58b863506", "parents": [ "c7cfa37b7324a190fc36ff116d79d0f899e8d273" ], "author": { "name": "David Rientjes", "email": "rientjes@google.com", "time": "Wed Mar 21 16:34:10 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Mar 21 17:54:59 2012 -0700" }, "message": "mm, memcg: pass charge order to oom killer\n\nThe oom killer typically displays the allocation order at the time of oom\nas a part of its diangostic messages (for global, cpuset, and mempolicy\nooms).\n\nThe memory controller may also pass the charge order to the oom killer so\nit can emit the same information.
