      "message": "sched, cputime: Introduce thread_group_times()\n\nThis is a real fix for problem of utime/stime values decreasing\ndescribed in the thread:\n\n   http://lkml.org/lkml/2009/11/3/522\n\nNow cputime is accounted in the following way:\n\n - {u,s}time in task_struct are increased every time when the thread\n   is interrupted by a tick (timer interrupt).\n\n - When a thread exits, its {u,s}time are added to signal-\u003e{u,s}time,\n   after adjusted by task_times().\n\n - When all threads in a thread_group exits, accumulated {u,s}time\n   (and also c{u,s}time) in signal struct are added to c{u,s}time\n   in signal struct of the group\u0027s parent.\n\nSo {u,s}time in task struct are \"raw\" tick count, while\n{u,s}time and c{u,s}time in signal struct are \"adjusted\" values.\n\nAnd accounted values are used by:\n\n - task_times(), to get cputime of a thread:\n   This function returns adjusted values that originates from raw\n   {u,s}time and scaled by sum_exec_runtime that accounted by CFS.\n\n - thread_group_cputime(), to get cputime of a thread group:\n   This function returns sum of all {u,s}time of living threads in\n   the group, plus {u,s}time in the signal struct that is sum of\n   adjusted cputimes of all exited threads belonged to the group.\n\nThe problem is the return value of thread_group_cputime(),\nbecause it is mixed sum of \"raw\" value and \"adjusted\" value:\n\n  group\u0027s {u,s}time \u003d foreach(thread){{u,s}time} + exited({u,s}time)\n\nThis misbehavior can break {u,s}time monotonicity.\nAssume that if there is a thread that have raw values greater\nthan adjusted values (e.g. interrupted by 1000Hz ticks 50 times\nbut only runs 45ms) and if it exits, cputime will decrease (e.g.\n-5ms).\n\nTo fix this, we could do:\n\n  group\u0027s {u,s}time \u003d foreach(t){task_times(t)} + exited({u,s}time)\n\nBut task_times() contains hard divisions, so applying it for\nevery thread should be avoided.\n\nThis patch fixes the above problem in the following way:\n\n - Modify thread\u0027s exit (\u003d __exit_signal()) not to use task_times().\n   It means {u,s}time in signal struct accumulates raw values instead\n   of adjusted values.  As the result it makes thread_group_cputime()\n   to return pure sum of \"raw\" values.\n\n - Introduce a new function thread_group_times(*task, *utime, *stime)\n   that converts \"raw\" values of thread_group_cputime() to \"adjusted\"\n   values, in same calculation procedure as task_times().\n\n - Modify group\u0027s exit (\u003d wait_task_zombie()) to use this introduced\n   thread_group_times().  It make c{u,s}time in signal struct to\n   have adjusted values like before this patch.\n\n - Replace some thread_group_cputime() by thread_group_times().\n   This replacements are only applied where conveys the \"adjusted\"\n   cputime to users, and where already uses task_times() near by it.\n   (i.e. sys_times(), getrusage(), and /proc/\u003cPID\u003e/stat.)\n\nThis patch have a positive side effect:\n\n - Before this patch, if a group contains many short-life threads\n   (e.g. runs 0.9ms and not interrupted by ticks), the group\u0027s\n   cputime could be invisible since thread\u0027s cputime was accumulated\n   after adjusted: imagine adjustment function as adj(ticks, runtime),\n     {adj(0, 0.9) + adj(0, 0.9) + ....} \u003d {0 + 0 + ....} \u003d 0.\n   After this patch it will not happen because the adjustment is\n   applied after accumulated.\n\nv2:\n - remove if()s, put new variables into signal_struct.\n\nSigned-off-by: Hidetoshi Seto \u003cseto.hidetoshi@jp.fujitsu.com\u003e\nAcked-by: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Spencer Candland \u003cspencer@bluehost.com\u003e\nCc: Americo Wang \u003cxiyou.wangcong@gmail.com\u003e\nCc: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: Balbir Singh \u003cbalbir@in.ibm.com\u003e\nCc: Stanislaw Gruszka \u003csgruszka@redhat.com\u003e\nLKML-Reference: \u003c4B162517.8040909@jp.fujitsu.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "rcu: Fix grace-period-stall bug on large systems with CPU hotplug\n\nWhen the last CPU of a given leaf rcu_node structure goes\noffline, all of the tasks queued on that leaf rcu_node structure\n(due to having blocked in their current RCU read-side critical\nsections) are requeued onto the root rcu_node structure.  This\nrequeuing is carried out by rcu_preempt_offline_tasks().\nHowever, it is possible that these queued tasks are the only\nthing preventing the leaf rcu_node structure from reporting a\nquiescent state up the rcu_node hierarchy.  Unfortunately, the\nold code would fail to do this reporting, resulting in a\ngrace-period stall given the following sequence of events:\n\n1.\tKernel built for more than 32 CPUs on 32-bit systems or for more\n\tthan 64 CPUs on 64-bit systems, so that there is more than one\n\trcu_node structure.  (Or CONFIG_RCU_FANOUT is artificially set\n\tto a number smaller than CONFIG_NR_CPUS.)\n\n2.\tThe kernel is built with CONFIG_TREE_PREEMPT_RCU.\n\n3.\tA task running on a CPU associated with a given leaf rcu_node\n\tstructure blocks while in an RCU read-side critical section\n\t-and- that CPU has not yet passed through a quiescent state\n\tfor the current RCU grace period.  This will cause the task\n\tto be queued on the leaf rcu_node\u0027s blocked_tasks[] array, in\n\tparticular, on the element of this array corresponding to the\n\tcurrent grace period.\n\n4.\tEach of the remaining CPUs corresponding to this same leaf rcu_node\n\tstructure pass through a quiescent state.  However, the task is\n\tstill in its RCU read-side critical section, so these quiescent\n\tstates cannot be reported further up the rcu_node hierarchy.\n\tNevertheless, all bits in the leaf rcu_node structure\u0027s -\u003eqsmask\n\tfield are now zero.\n\n5.\tEach of the remaining CPUs go offline.  (The events in step\n\t#4 and #5 can happen in any order as long as each CPU passes\n\tthrough a quiescent state before going offline.)\n\n6.\tWhen the last CPU goes offline, __rcu_offline_cpu() will invoke\n\trcu_preempt_offline_tasks(), which will move the task to the\n\troot rcu_node structure, but without reporting a quiescent state\n\tup the rcu_node hierarchy (and this failure to report a quiescent\n\tstate is the bug).\n\n\tBut because this leaf rcu_node structure\u0027s -\u003eqsmask field is\n\talready zero and its -\u003eblock_tasks[] entries are all empty,\n\tforce_quiescent_state() will skip this rcu_node structure.\n\n\tTherefore, grace periods are now hung.\n\nThis patch abstracts some code out of rcu_read_unlock_special(),\ncalling the result task_quiet() by analogy with cpu_quiet(), and\ninvokes task_quiet() from both rcu_read_lock_special() and\n__rcu_offline_cpu().  Invoking task_quiet() from\n__rcu_offline_cpu() reports the quiescent state up the rcu_node\nhierarchy, fixing the bug.  This ends up requiring a separate\nlock_class_key per level of the rcu_node hierarchy, which this\npatch also provides.\n\nSigned-off-by: Paul E.
