      "message": "sched: cpu accounting controller (V2)\n\nCommit cfb5285660aad4931b2ebbfa902ea48a37dfffa1 removed a useful feature for\nus, which provided a cpu accounting resource controller.  This feature would be\nuseful if someone wants to group tasks only for accounting purpose and doesnt\nreally want to exercise any control over their cpu consumption.\n\nThe patch below reintroduces the feature. It is based on Paul Menage\u0027s\noriginal patch (Commit 62d0df64065e7c135d0002f069444fbdfc64768f), with\nthese differences:\n\n        - Removed load average information. I felt it needs more thought (esp\n\t  to deal with SMP and virtualized platforms) and can be added for\n\t  2.6.25 after more discussions.\n        - Convert group cpu usage to be nanosecond accurate (as rest of the cfs\n\t  stats are) and invoke cpuacct_charge() from the respective scheduler\n\t  classes\n\t- Make accounting scalable on SMP systems by splitting the usage\n\t  counter to be per-cpu\n\t- Move the code from kernel/cpu_acct.c to kernel/sched.c (since the\n\t  code is not big enough to warrant a new file and also this rightly\n\t  needs to live inside the scheduler. Also things like accessing\n\t  rq-\u003elock while reading cpu usage becomes easier if the code lived in\n\t  kernel/sched.c)\n\nThe patch also modifies the cpu controller not to provide the same accounting\ninformation.\n\nTested-by: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\n\n Tested the patches on top of 2.6.24-rc3. The patches work fine. Ran\n some simple tests like cpuspin (spin on the cpu), ran several tasks in\n the same group and timed them. Compared their time stamps with\n cpuacct.usage.\n\nSigned-off-by: Srivatsa Vaddagiri \u003cvatsa@linux.vnet.ibm.com\u003e\nSigned-off-by: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

This causes a a new child\n  to be created, also a new group (do_fork-\u003ecopy_namespaces-\u003ens_cgroup_clone-\u003e\n  cgroup_clone) and the child is attached to the new group (cgroup_clone-\u003e\n  attach_task-\u003esched_move_task). At this point in time, the child\u0027s scheduler \n  related fields are uninitialized (including its on_rq field, which it has\n  inherited from parent). As a result sched_move_task thinks its on\n  runqueue, when it isn\u0027t.\n\n  As a solution to this problem, I moved sched_fork() call, which\n  initializes scheduler related fields on a new task, before\n  copy_namespaces(). I am not sure though whether moving up will\n  cause other side-effects. Do you see any issue?\n\n- The second problem exposed by this test is that task_new_fair()\n  assumes that parent and child will be part of the same group (which \n  needn\u0027t be as this test shows). As a result, cfs_rq-\u003ecurr can be NULL\n  for the child.\n\n  The solution is to test for curr pointer being NULL in\n  task_new_fair().\n\nWith the patch below, I could run ns_exec() fine w/o a crash.\n\nReported-by: Sukadev Bhattiprolu \u003csukadev@us.ibm.com\u003e\nSigned-off-by: Srivatsa Vaddagiri \u003cvatsa@linux.vnet.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"
