      "message": "sched, delay accounting: fix incorrect delay time when constantly waiting on runqueue\n\nThis patch corrects the incorrect value of per process run-queue wait\ntime reported by delay statistics. The anomaly was due to the following\nreason. When a process leaves the CPU and immediately starts waiting for\nCPU on the runqueue (which means it remains in the TASK_RUNNABLE state),\nthe time of re-entry into the run-queue is never recorded. Due to this,\nthe waiting time on the runqueue from this point of re-entry upto the\nnext time it hits the CPU is not accounted for. This is solved by\nrecording the time of re-entry of a process leaving the CPU in the\nsched_info_depart() function IF the process will go back to waiting on\nthe run-queue. This IF condition is verified by checking whether the\nprocess is still in the TASK_RUNNABLE state.\n\nThe patch was tested on 2.6.26-rc6 using two simple CPU hog programs.\nThe values noted prior to the fix did not account for the time spent on\nthe runqueue waiting. After the fix, the correct values were reported\nback to user space.\n\nSigned-off-by: Bharath Ravi \u003cbharathravi1@gmail.com\u003e\nSigned-off-by: Madhava K R  \u003cmadhavakr@gmail.com\u003e\nCc: dhaval@linux.vnet.ibm.com\nCc: vatsa@in.ibm.com\nCc: balbir@in.ibm.com\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "softlockup: fix NMI hangs due to lock race - 2.6.26-rc regression\n\nThe touch_nmi_watchdog() routine on x86 ultimately calls\ntouch_softlockup_watchdog().  The problem is that to touch the\nsoftlockup watchdog, the cpu_clock code has to be called which could\ninvolve multiple cpu locks and can lead to a hard hang if one of the\nlocks is held by a processor that is not going to return anytime soon\n(such as could be the case with kgdb or perhaps even with some other\nkind of exception).\n\nThis patch causes the public version of the\ntouch_softlockup_watchdog() to defer the cpu clock access to a later\npoint.\n\nThe test case for this problem is to use the following kernel config\noptions:\n\nCONFIG_KGDB_TESTS\u003dy\nCONFIG_KGDB_TESTS_ON_BOOT\u003dy\nCONFIG_KGDB_TESTS_BOOT_STRING\u003d\"V1F100I100000\"\n\nIt should be noted that kgdb test suite and these options were not\navailable until 2.6.26-rc2, so it was necessary to patch the kgdb\ntest suite during the bisection.\n\nI would consider this patch a regression fix because the problem first\nappeared in commit 27ec4407790d075c325e1f4da0a19c56953cce23 when some\nlogic was added to try to periodically sync the clocks.  It was\npossible to work around this particular problem by simply not\nperforming the sync anytime the system was in a critical context.\nThis was ok until commit 3e51f33fcc7f55e6df25d15b55ed10c8b4da84cd,\nwhich added config option CONFIG_HAVE_UNSTABLE_SCHED_CLOCK and some\nmulti-cpu locks to sync the clocks.  It became clear that accessing\nthis code from an nmi was the source of the lockups.  Avoiding the\naccess to the low level clock code from an code inside the NMI\nprocessing also fixed the problem with the 27ec44... commit.\n\nSigned-off-by: Jason Wessel \u003cjason.wessel@windriver.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "sched: CPU hotplug events must not destroy scheduler domains created by the cpusets\n\nFirst issue is not related to the cpusets. We\u0027re simply leaking doms_cur.\nIt\u0027s allocated in arch_init_sched_domains() which is called for every\nhotplug event. So we just keep reallocation doms_cur without freeing it.\nI introduced free_sched_domains() function that cleans things up.\n\nSecond issue is that sched domains created by the cpusets are\ncompletely destroyed by the CPU hotplug events. For all CPU hotplug\nevents scheduler attaches all CPUs to the NULL domain and then puts\nthem all into the single domain thereby destroying domains created\nby the cpusets (partition_sched_domains).\nThe solution is simple, when cpusets are enabled scheduler should not\ncreate default domain and instead let cpusets do that.

      "message": "ftrace: user update and disable dynamic ftrace daemon\n\nIn dynamic ftrace, the mcount function starts off pointing to a stub\nfunction that just returns.\n\nOn start up, the call to the stub is modified to point to a \"record_ip\"\nfunction. The job of the record_ip function is to add the function to\na pre-allocated hash list. If the function is already there, it simply is\nignored, otherwise it is added to the list.\n\nLater, a ftraced daemon wakes up and calls kstop_machine if any functions\nhave been recorded, and changes the calls to the recorded functions to\na simple nop.  If no functions were recorded, the daemon goes back to sleep.\n\nThe daemon wakes up once a second to see if it needs to update any newly\nrecorded functions into nops.  Usually it does not, but if a lot of code\nhas been executed for the first time in the kernel, the ftraced daemon\nwill call kstop_machine to update those into nops.\n\nThe problem currently is that there\u0027s no way to stop the daemon from doing\nthis, and it can cause unneeded latencies (800us which for some is bothersome).\n\nThis patch adds a new file /debugfs/tracing/ftraced_enabled. If the daemon\nis active, reading this will return \"enabled\\n\" and \"disabled\\n\" when the\ndaemon is not running. To disable the daemon, the user can echo \"0\" or\n\"disable\" into this file, and \"1\" or \"enable\" to re-enable the daemon.\n\nSince the daemon is used to convert the functions into nops to increase\nthe performance of the system, I also added that anytime something is\nwritten into the ftraced_enabled file, kstop_machine will run if there\nare new functions that have been detected that need to be converted.\n\nThis way the user can disable the daemon but still be able to control the\nconversion of the mcount calls to nops by simply,\n\n  \"echo 0 \u003e /debugfs/tracing/ftraced_enabled\"\n\nwhen they need to do more conversions.\n\nTo see the number of converted functions:\n\n  \"cat /debugfs/tracing/dyn_ftrace_total_info\"\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

E.g, consider the correct trace of the following sequence:\n\ndo_IRQ()\n{\n~\n  irq_enter();\n~\n}\n\nTrace log (sample):\n\u003cidle\u003e-0     [00] 4154504455.781616: irq_enter \u003c- do_IRQ\n\nBut if irq_enter() has a kretprobe installed on it, the return value stored on the stack at each invocation is modified to divert the return to a kprobe trampoline function called kretprobe_trampoline(). So with this the trace would (currently) look like:\n\n\u003cidle\u003e-0     [00] 4154504455.781616: irq_enter \u003c- kretprobe_trampoline\n\nNow this is quite misleading to the end user, as it suggests something that didn\u0027t actually happen.

It is similar to adding \u0027notrace\u0027 to those\nfunctions but by doing it without recompiling the kernel.\n\nHere\u0027s how set_ftrace_filter and set_ftrace_notrace interact. Remember, if\nset_ftrace_filter is set, it removes all functions from the trace execpt for\nthose listed in the set_ftrace_filter. set_ftrace_notrace will prevent those\nfunctions from being traced.\n\nIf you were to set one function in both set_ftrace_filter and\nset_ftrace_notrace and that function was the same, then you would end up\nwith an empty trace.\n\nthe set of functions to trace is:\n\n  set_ftrace_filter \u003d\u003d empty then\n\n     all functions not in set_ftrace_notrace\n\n  else\n\n     set of the set_ftrace_filter and not in set of set_ftrace_notrace.\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n"
