Dear Matthew, First, thank you so much for your review and comments.
I totally agree with you.
Yes, initially I included process-name but later removed it to shrink
some lines.
I thought just pid should be enough to figure out the culprit process
from dumps.
Okay, I agree __func__ can also be removed.
ppid, I thought might be useful, so I included it. Okay I will remove
that too.

Okay, yes I think this should be sufficient.
But I think printing pages also should be good to indicate the users to
lack
information about this commitment.

Sorry, this part about dup_mmap(), I could not understand.


Thanks,
