      "message": "tracing, sched: LTTng instrumentation - scheduler\n\nInstrument the scheduler activity (sched_switch, migration, wakeups,\nwait for a task, signal delivery) and process/thread\ncreation/destruction (fork, exit, kthread stop). Actually, kthread\ncreation is not instrumented in this patch because it is architecture\ndependent. It allows to connect tracers such as ftrace which detects\nscheduling latencies, good/bad scheduler decisions. Tools like LTTng can\nexport this scheduler information along with instrumentation of the rest\nof the kernel activity to perform post-mortem analysis on the scheduler\nactivity.\n\nAbout the performance impact of tracepoints (which is comparable to\nmarkers), even without immediate values optimizations, tests done by\nHideo Aoki on ia64 show no regression. His test case was using hackbench\non a kernel where scheduler instrumentation (about 5 events in code\nscheduler code) was added. See the \"Tracepoints\" patch header for\nperformance result detail.\n\nChangelog :\n\n- Change instrumentation location and parameter to match ftrace\n  instrumentation, previously done with kernel markers.\n\n[ mingo@elte.hu: conflict resolutions ]\nSigned-off-by: Mathieu Desnoyers \u003cmathieu.desnoyers@polymtl.ca\u003e\nAcked-by: \u0027Peter Zijlstra\u0027 \u003cpeterz@infradead.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"
