  "message": "tracing: move function profiler data out of function struct\n\nImpact: reduce size of memory in function profiler\n\nThe function profiler originally introduces its counters into the\nfunction records itself. There is 20 thousand different functions on\na normal system, and that is adding 20 thousand counters for profiling\nevent when not needed.\n\nA normal run of the profiler yields only a couple of thousand functions\nexecuted, depending on what is being profiled. This means we have around\n18 thousand useless counters.\n\nThis patch rectifies this by moving the data out of the function\nrecords used by dynamic ftrace. Data is preallocated to hold the functions\nwhen the profiling begins. Checks are made during profiling to see if\nmore recorcds should be allocated, and they are allocated if it is safe\nto do so.\n\nThis also removes the dependency from using dynamic ftrace, and also\nremoves the overhead by having it enabled.\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\n",
