  "message": "tracing: Do not enable function event with enable\n\nWith the adding of function tracing event to perf, it caused a\nside effect that produces the following warning when enabling all\nevents in ftrace:\n\n # echo 1 \u003e /sys/kernel/debug/tracing/events/enable\n\n[console]\nevent trace: Could not enable event function\n\nThis is because when enabling all events via the debugfs system\nit ignores events that do not have a -\u003ereg() function assigned.\nThis was to skip over the ftrace internal events (as they are\nnot TRACE_EVENTs). But as the ftrace function event now has\na -\u003ereg() function attached to it for use with perf, it is no\nlonger ignored.\n\nWorse yet, this -\u003ereg() function is being called when it should\nnot be. It returns an error and causes the above warning to\nbe printed.\n\nBy adding a new event_call flag (TRACE_EVENT_FL_IGNORE_ENABLE)\nand have all ftrace internel event structures have it set,\nsetting the events/enable will no longe try to incorrectly enable\nthe function event and does not warn.\n\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n",
