Hello,
 
The example included in libpfm-4.3.0 doesn't work while executed with '-i'(inherit) option.
 
$HOME/libpfm-4.3.0/perf_examples/task_smpl -i ...
<output>:
task_smpl: cannot mmap buffer: Invalid argument
 
The machine is Intel(R) Xeon(R) CPU E5520.
 
What should I do to fix it?
Thanks very much!
