I.e. we would have the test:
if (!(event->header.misc & PERF_RECORD_MISC_SWITCH_NEXT_PREV_PID))
return fprintf(fp, " %s\n", in_out);

Here too:
if (event->header.misc & PERF_RECORD_MISC_SWITCH_NEXT_PREV_PID) {
event->context_switch.next_prev_pid =
bswap_32(event->context_switch.next_prev_pid);
event->context_switch.next_prev_tid =
bswap_32(event->context_switch.next_prev_tid);
if (sample_id_all)
swap_sample_id_all(event, &event->context_switch + 1);
} else if (sample_id_all)
swap_sample_id_all(event, &event->header + 1);
