      7 Test to determine if the kernel's perf event architecture can handle
      8 a process changing its name and still attribute the samples to a binary.
      9 
     10 A test program which changes its name using prctl runs under perf and runs
     11 through a computational crc loop in order to ensure it gets some samples.
     12 Perf produces a data file from that run, and that data file is run through
     13 perf again to produce a report.  The report is checked to see that the samples
     14 were not marked "unknown".
