Introduce the perf_event__synthesize_stat function to synthesize a 'struct stat_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/1445784728-21732-16-git-send-email-jolsa@kernel.org [ Renamed 'stat' parameter to 'st' to fix 'already defined' build error with older distros (e.g. RHEL6.7) ] Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
