perf ftrace: Make 'function_graph' be the default tracerperf-core-for-mingo-4.11-20170126
So that we can suppress the '-t function_graph' and get a more compact command line: # perf ftrace usleep 123456 | grep raw_spin_lock | sort -k2 -nr | head -5 2) 0.555 us | _raw_spin_lock(); 2) 0.516 us | _raw_spin_lock(); 2) 0.410 us | _raw_spin_lock_irq(); 2) 0.374 us | _raw_spin_lock_irqsave(); # Tested-by: Masami Hiramatsu <mhiramat@kernel.org> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Jeremy Eder <jeder@redhat.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Stephane Eranian <eranian@google.com> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/n/tip-ss9xgx5htpxcv86x42pnh3m6@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
