perf annotate: Print the evsel name in the stdio output
So that when showing multiple events annotations, we can figure out which is which: # perf record -a -e instructions,cycles sleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.826 MB perf.data (~36078 samples) ] # perf evlist instructions cycles # perf annotate intel_idle 2> /dev/null | head -1 Percent | Source code & Disassembly of vmlinux for instructions # Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/n/tip-n1r51l329434js84qtb2c6l9@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
