- * This test will generate random numbers of calls to some getpid syscalls,
- * then establish an mmap for a group of events that are created to monitor
- * the syscalls.
- *
- * It will receive the events, using mmap, use its PERF_SAMPLE_ID generated
- * sample.id field to map back to its respective perf_evsel instance.
- *
- * Then it checks if the number of syscalls reported as perf events by
- * the kernel corresponds to the number of syscalls made.
