Here it is:

- while ((dent = readdir(dir))) {
- if (dent->d_type != DT_DIR ||
- strcmp(dent->d_name, ".") == 0 ||
- strcmp(dent->d_name, "..") == 0 ||
- strcmp(dent->d_name, "ftrace") == 0 ||
+ for_each_event(dir, dent, tps) {
+ if (strcmp(dent->d_name, "ftrace") == 0 ||
!system_in_tp_list(dent->d_name, tps))
continue;
