perf tools: Add stat round event synthesize function
Introduce the perf_event__synthesize_stat_round function to synthesize a 'struct stat_round_event'. Signed-off-by: Jiri Olsa <jolsa@kernel.org> Tested-by: Kan Liang <kan.liang@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/1445784728-21732-19-git-send-email-jolsa@kernel.org [ Renamed 'time' parameter to 'evtime' to fix build on older systems ] Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
