      "message": "cgroups: add an owner to the mm_struct\n\nRemove the mem_cgroup member from mm_struct and instead adds an owner.\n\nThis approach was suggested by Paul Menage.  The advantage of this approach\nis that, once the mm-\u003eowner is known, using the subsystem id, the cgroup\ncan be determined.  It also allows several control groups that are\nvirtually grouped by mm_struct, to exist independent of the memory\ncontroller i.e., without adding mem_cgroup\u0027s for each controller, to\nmm_struct.\n\nA new config option CONFIG_MM_OWNER is added and the memory resource\ncontroller selects this config option.\n\nThis patch also adds cgroup callbacks to notify subsystems when mm-\u003eowner\nchanges.  The mm_cgroup_changed callback is called with the task_lock() of\nthe new task held and is called just prior to changing the mm-\u003eowner.\n\nI am indebted to Paul Menage for the several reviews of this patchset and\nhelping me make it lighter and simpler.\n\nThis patch was tested on a powerpc box, it was compiled with both the\nMM_OWNER config turned on and off.\n\nAfter the thread group leader exits, it\u0027s moved to init_css_state by\ncgroup_exit(), thus all future charges from runnings threads would be\nredirected to the init_css_set\u0027s subsystem.\n\nSigned-off-by: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\nCc: Pavel Emelianov \u003cxemul@openvz.org\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Sudhir Kumar \u003cskumar@linux.vnet.ibm.com\u003e\nCc: YAMAMOTO Takashi \u003cyamamoto@valinux.co.jp\u003e\nCc: Hirokazu Takahashi \u003ctaka@valinux.co.jp\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e,\nCc: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\nAcked-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nAcked-by: Pekka Enberg \u003cpenberg@cs.helsinki.fi\u003e\nReviewed-by: Paul Menage \u003cmenage@google.com\u003e\nCc: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

The\npatch is on top of 2.6.21-mm1 with Paul\u0027s cgroups v9 patches (forward\nported)\n\nThis patch implements per cgroup statistics infrastructure and re-uses\ncode from the taskstats interface.  A new set of cgroup operations are\nregistered with commands and attributes.  It should be very easy to\n*extend* per cgroup statistics, by adding members to the cgroupstats\nstructure.\n\nThe current model for cgroupstats is a pull, a push model (to post\nstatistics on interesting events), should be very easy to add.  Currently\nuser space requests for statistics by passing the cgroup file\ndescriptor.  Statistics about the state of all the tasks in the cgroup\nis returned to user space.\n\nTODO\u0027s/NOTE:\n\nThis patch provides an infrastructure for implementing cgroup statistics.\nBased on the needs of each controller, we can incrementally add more statistics,\nevent based support for notification of statistics, accumulation of taskstats\ninto cgroup statistics in the future.\n\nSample output\n\n# ./cgroupstats -C /cgroup/a\nsleeping 2, blocked 0, running 1, stopped 0, uninterruptible 0\n\n# ./cgroupstats -C /cgroup/\nsleeping 154, blocked 0, running 0, stopped 0, uninterruptible 0\n\nIf the approach looks good, I\u0027ll enhance and post the user space utility for\nthe same\n\nFeedback, comments, test results are always welcome!\n\n[akpm@linux-foundation.org: build fix]\nSigned-off-by: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\nCc: Paul Menage \u003cmenage@google.com\u003e\nCc: Jay Lan \u003cjlan@engr.sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "Task Control Groups: basic task cgroup framework\n\nGeneric Process Control Groups\n--------------------------\n\nThere have recently been various proposals floating around for\nresource management/accounting and other task grouping subsystems in\nthe kernel, including ResGroups, User BeanCounters, NSProxy\ncgroups, and others.  These all need the basic abstraction of being\nable to group together multiple processes in an aggregate, in order to\ntrack/limit the resources permitted to those processes, or control\nother behaviour of the processes, and all implement this grouping in\ndifferent ways.\n\nThis patchset provides a framework for tracking and grouping processes\ninto arbitrary \"cgroups\" and assigning arbitrary state to those\ngroupings, in order to control the behaviour of the cgroup as an\naggregate.\n\nThe intention is that the various resource management and\nvirtualization/cgroup efforts can also become task cgroup\nclients, with the result that:\n\n- the userspace APIs are (somewhat) normalised\n\n- it\u0027s easier to test e.g. the ResGroups CPU controller in\n conjunction with the BeanCounters memory controller, or use either of\nthem as the resource-control portion of a virtual server system.\n\n- the additional kernel footprint of any of the competing resource\n management systems is substantially reduced, since it doesn\u0027t need\n to provide process grouping/containment, hence improving their\n chances of getting into the kernel\n\nThis patch:\n\nAdd the main task cgroups framework - the cgroup filesystem, and the\nbasic structures for tracking membership and associating subsystem state\nobjects to tasks.\n\nSigned-off-by: Paul Menage \u003cmenage@google.com\u003e\nCc: Serge E.
