So the PG_compound_lock can\nbe added to page-\u003eflags without overflowing (because of the sparse section\nbits increasing) with CONFIG_X86_PAE\u003dy and CONFIG_X86_PAT\u003dy.  This also\nhas to move the memory hotplug code from _mapcount to lru.next to avoid\nany risk of clashes.  We can\u0027t use lru.next for PG_buddy removal, but\nmemory hotplug can use lru.next even more easily than the mapcount\ninstead.\n\nSigned-off-by: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

Currently, it is not possible to oom_adj\ndown without CAP_SYS_RESOURCE.  This patch allows a task to decrease its\noom_score_adj back to the value that a CAP_SYS_RESOURCE thread set it to\nor its inherited value at fork.  Assuming the thread that has forked it\nhas oom_score_adj of 0, each process could decrease it back from 0 upon\nactivation unless a CAP_SYS_RESOURCE thread elevated it to something\nhigher.\n\nAlternative considered:\n\n* a setuid binary\n* a daemon with CAP_SYS_RESOURCE\n\nSince you don\u0027t wan\u0027t all processes to be able to reduce their oom_adj, a\nsetuid or daemon implementation would be complex.  The alternatives also\nhave much higher overhead.\n\nThis patch updated from original patch based on feedback from David\nRientjes.\n\nSigned-off-by: Mandeep Singh Baines \u003cmsb@chromium.org\u003e\nAcked-by: David Rientjes \u003crientjes@google.com\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Ying Han \u003cyinghan@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "fs: rcu-walk for path lookup\n\nPerform common cases of path lookups without any stores or locking in the\nancestor dentry elements. This is called rcu-walk, as opposed to the current\nalgorithm which is a refcount based walk, or ref-walk.\n\nThis results in far fewer atomic operations on every path element,\nsignificantly improving path lookup performance. It also avoids cacheline\nbouncing on common dentries, significantly improving scalability.\n\nThe overall design is like this:\n* LOOKUP_RCU is set in nd-\u003eflags, which distinguishes rcu-walk from ref-walk.\n* Take the RCU lock for the entire path walk, starting with the acquiring\n  of the starting path (eg. root/cwd/fd-path). So now dentry refcounts are\n  not required for dentry persistence.\n* synchronize_rcu is called when unregistering a filesystem, so we can\n  access d_ops and i_ops during rcu-walk.\n* Similarly take the vfsmount lock for the entire path walk. So now mnt\n  refcounts are not required for persistence. Also we are free to perform mount\n  lookups, and to assume dentry mount points and mount roots are stable up and\n  down the path.\n* Have a per-dentry seqlock to protect the dentry name, parent, and inode,\n  so we can load this tuple atomically, and also check whether any of its\n  members have changed.\n* Dentry lookups (based on parent, candidate string tuple) recheck the parent\n  sequence after the child is found in case anything changed in the parent\n  during the path walk.\n* inode is also RCU protected so we can load d_inode and use the inode for\n  limited things.\n* i_mode, i_uid, i_gid can be tested for exec permissions during path walk.\n* i_op can be loaded.\n\nWhen we reach the destination dentry, we lock it, recheck lookup sequence,\nand increment its refcount and mountpoint refcount. RCU and vfsmount locks\nare dropped. This is termed \"dropping rcu-walk\". If the dentry refcount does\nnot match, we can not drop rcu-walk gracefully at the current point in the\nlokup, so instead return -ECHILD (for want of a better errno). This signals the\npath walking code to re-do the entire lookup with a ref-walk.\n\nAside from the final dentry, there are other situations that may be encounted\nwhere we cannot continue rcu-walk. In that case, we drop rcu-walk (ie. take\na reference on the last good dentry) and continue with a ref-walk. Again, if\nwe can drop rcu-walk gracefully, we return -ECHILD and do the whole lookup\nusing ref-walk. But it is very important that we can continue with ref-walk\nfor most cases, particularly to avoid the overhead of double lookups, and to\ngain the scalability advantages on common path elements (like cwd and root).\n\nThe cases where rcu-walk cannot continue are:\n* NULL dentry (ie. any uncached path element)\n* parent with d_inode-\u003ei_op-\u003epermission or ACLs\n* dentries with d_revalidate\n* Following links\n\nIn future patches, permission checks and d_revalidate become rcu-walk aware. It\nmay be possible eventually to make following links rcu-walk aware.\n\nUncached path elements will always require dropping to ref-walk mode, at the\nvery least because i_mutex needs to be grabbed, and objects allocated.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@kernel.dk\u003e\n"

      "message": "fs: icache RCU free inodes\n\nRCU free the struct inode. This will allow:\n\n- Subsequent store-free path walking patch. The inode must be consulted for\n  permissions when walking, so an RCU inode reference is a must.\n- sb_inode_list_lock to be moved inside i_lock because sb list walkers who want\n  to take i_lock no longer need to take sb_inode_list_lock to walk the list in\n  the first place. This will simplify and optimize locking.\n- Could remove some nested trylock loops in dcache code\n- Could potentially simplify things a bit in VM land. Do not need to take the\n  page lock to follow page-\u003emapping.\n\nThe downsides of this is the performance cost of using RCU. In a simple\ncreat/unlink microbenchmark, performance drops by about 10% due to inability to\nreuse cache-hot slab objects. As iterations increase and RCU freeing starts\nkicking over, this increases to about 20%.\n\nIn cases where inode lifetimes are longer (ie. many inodes may be allocated\nduring the average life span of a single inode), a lot of this cache reuse is\nnot applicable, so the regression caused by this patch is smaller.\n\nThe cache-hot regression could largely be avoided by using SLAB_DESTROY_BY_RCU,\nhowever this adds some complexity to list walking and store-free path walking,\nso I prefer to implement this at a later date, if it is shown to be a win in\nreal situations.

      "message": "sched: Add \u0027autogroup\u0027 scheduling feature: automated per session task groups\n\nA recurring complaint from CFS users is that parallel kbuild has\na negative impact on desktop interactivity.  This patch\nimplements an idea from Linus, to automatically create task\ngroups.  Currently, only per session autogroups are implemented,\nbut the patch leaves the way open for enhancement.\n\nImplementation: each task\u0027s signal struct contains an inherited\npointer to a refcounted autogroup struct containing a task group\npointer, the default for all tasks pointing to the\ninit_task_group.  When a task calls setsid(), a new task group\nis created, the process is moved into the new task group, and a\nreference to the preveious task group is dropped.  Child\nprocesses inherit this task group thereafter, and increase it\u0027s\nrefcount.  When the last thread of a process exits, the\nprocess\u0027s reference is dropped, such that when the last process\nreferencing an autogroup exits, the autogroup is destroyed.\n\nAt runqueue selection time, IFF a task has no cgroup assignment,\nits current autogroup is used.\n\nAutogroup bandwidth is controllable via setting it\u0027s nice level\nthrough the proc filesystem:\n\n  cat /proc/\u003cpid\u003e/autogroup\n\nDisplays the task\u0027s group and the group\u0027s nice level.\n\n  echo \u003cnice level\u003e \u003e /proc/\u003cpid\u003e/autogroup\n\nSets the task group\u0027s shares to the weight of nice \u003clevel\u003e task.\nSetting nice level is rate limited for !admin users due to the\nabuse risk of task group locking.\n\nThe feature is enabled from boot by default if\nCONFIG_SCHED_AUTOGROUP\u003dy is selected, but can be disabled via\nthe boot option noautogroup, and can also be turned on/off on\nthe fly via:\n\n  echo [01] \u003e /proc/sys/kernel/sched_autogroup_enabled\n\n... which will automatically move tasks to/from the root task group.\n\nSigned-off-by: Mike Galbraith \u003cefault@gmx.de\u003e\nAcked-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Markus Trippelsdorf \u003cmarkus@trippelsdorf.de\u003e\nCc: Mathieu Desnoyers \u003cmathieu.desnoyers@efficios.com\u003e\nCc: Paul Turner \u003cpjt@google.com\u003e\nCc: Oleg Nesterov \u003coleg@redhat.com\u003e\n[ Removed the task_group_path() debug code, and fixed !EVENTFD build failure. ]\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nLKML-Reference: \u003c1290281700.28711.9.camel@maggy.simson.net\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "llseek: automatically add .llseek fop\n\nAll file_operations should get a .llseek operation so we can make\nnonseekable_open the default for future file operations without a\n.llseek pointer.\n\nThe three cases that we can automatically detect are no_llseek, seq_lseek\nand default_llseek. For cases where we can we can automatically prove that\nthe file offset is always ignored, we use noop_llseek, which maintains\nthe current behavior of not returning an error from a seek.\n\nNew drivers should normally not use noop_llseek but instead use no_llseek\nand call nonseekable_open at open time.  Existing drivers can be converted\nto do the same when the maintainer knows for certain that no user code\nrelies on calling seek on the device file.\n\nThe generated code is often incorrectly indented and right now contains\ncomments that clarify for each added line why a specific variant was\nchosen. In the version that gets submitted upstream, the comments will\nbe gone and I will manually fix the indentation, because there does not\nseem to be a way to do that using coccinelle.\n\nSome amount of new code is currently sitting in linux-next that should get\nthe same modifications, which I will do at the end of the merge window.\n\nMany thanks to Julia Lawall for helping me learn to write a

This changes it back to use default_llseek\nin order to restore the original behaviour.\n\nThe problem with generic_file_llseek is that it only allows seeks up to\ninode-\u003ei_sb-\u003es_maxbytes, which is zero on procfs and some other virtual\nfile systems.  We should merge generic_file_llseek and default_llseek some\nday and clean this up in a proper way, but for 2.6.35/36, reverting vmcore\nis the safer solution.\n\nSigned-off-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nReported-by: CAI Qian \u003ccaiqian@redhat.com\u003e\nTested-by: CAI Qian \u003ccaiqian@redhat.com\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "mm: fix up some user-visible effects of the stack guard page\n\nThis commit makes the stack guard page somewhat less visible to user\nspace. It does this by:\n\n - not showing the guard page in /proc/\u003cpid\u003e/maps\n\n   It looks like lvm-tools will actually read /proc/self/maps to figure\n   out where all its mappings are, and effectively do a specialized\n   \"mlockall()\" in user space.  By not showing the guard page as part of\n   the mapping (by just adding PAGE_SIZE to the start for grows-up\n   pages), lvm-tools ends up not being aware of it.\n\n - by also teaching the _real_ mlock() functionality not to try to lock\n   the guard page.\n\n   That would just expand the mapping down to create a new guard page,\n   so there really is no point in trying to lock it in place.\n\nIt would perhaps be nice to show the guard page specially in\n/proc/\u003cpid\u003e/maps (or at least mark grow-down segments some way), but\nlet\u0027s not open ourselves up to more breakage by user space from programs\nthat depends on the exact deails of the \u0027maps\u0027 file.\n\nSpecial thanks to Henrique de Moraes Holschuh for diving into lvm-tools\nsource code to see what was going on with the whole new warning.\n\nReported-and-tested-by: François Valenduc \u003cfrancois.valenduc@tvcablenet.be\nReported-by: Henrique de Moraes Holschuh \u003chmh@hmh.eng.br\u003e\nCc: stable@kernel.org\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "oom: badness heuristic rewrite\n\nThis a complete rewrite of the oom killer\u0027s badness() heuristic which is\nused to determine which task to kill in oom conditions.  The goal is to\nmake it as simple and predictable as possible so the results are better\nunderstood and we end up killing the task which will lead to the most\nmemory freeing while still respecting the fine-tuning from userspace.\n\nInstead of basing the heuristic on mm-\u003etotal_vm for each task, the task\u0027s\nrss and swap space is used instead.  This is a better indication of the\namount of memory that will be freeable if the oom killed task is chosen\nand subsequently exits.  This helps specifically in cases where KDE or\nGNOME is chosen for oom kill on desktop systems instead of a memory\nhogging task.\n\nThe baseline for the heuristic is a proportion of memory that each task is\ncurrently using in memory plus swap compared to the amount of \"allowable\"\nmemory.  \"Allowable,\" in this sense, means the system-wide resources for\nunconstrained oom conditions, the set of mempolicy nodes, the mems\nattached to current\u0027s cpuset, or a memory controller\u0027s limit.  The\nproportion is given on a scale of 0 (never kill) to 1000 (always kill),\nroughly meaning that if a task has a badness() score of 500 that the task\nconsumes approximately 50% of allowable memory resident in RAM or in swap\nspace.\n\nThe proportion is always relative to the amount of \"allowable\" memory and\nnot the total amount of RAM systemwide so that mempolicies and cpusets may\noperate in isolation; they shall not need to know the true size of the\nmachine on which they are running if they are bound to a specific set of\nnodes or mems, respectively.\n\nRoot tasks are given 3% extra memory just like __vm_enough_memory()\nprovides in LSMs.  In the event of two tasks consuming similar amounts of\nmemory, it is generally better to save root\u0027s task.\n\nBecause of the change in the badness() heuristic\u0027s baseline, it is also\nnecessary to introduce a new user interface to tune it.  It\u0027s not possible\nto redefine the meaning of /proc/pid/oom_adj with a new scale since the\nABI cannot be changed for backward compatability.  Instead, a new tunable,\n/proc/pid/oom_score_adj, is added that ranges from -1000 to +1000.  It may\nbe used to polarize the heuristic such that certain tasks are never\nconsidered for oom kill while others may always be considered.  The value\nis added directly into the badness() score so a value of -500, for\nexample, means to discount 50% of its memory consumption in comparison to\nother tasks either on the system, bound to the mempolicy, in the cpuset,\nor sharing the same memory controller.\n\n/proc/pid/oom_adj is changed so that its meaning is rescaled into the\nunits used by /proc/pid/oom_score_adj, and vice versa.  Changing one of\nthese per-task tunables will rescale the value of the other to an\nequivalent meaning.  Although /proc/pid/oom_adj was originally defined as\na bitshift on the badness score, it now shares the same linear growth as\n/proc/pid/oom_score_adj but with different granularity.  This is required\nso the ABI is not broken with userspace applications and allows oom_adj to\nbe deprecated for future removal.\n\nSigned-off-by: David Rientjes \u003crientjes@google.com\u003e\nCc: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: Balbir Singh \u003cbalbir@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
