    Hi Sandeep,

      
      This should be possible using ftrace without touching the code. I
      am not sure how to trigger on a specific function but I think it
      should be possible. Have a look at Documentation/trace/ftrace.txt

      
      andi

        dump_stack() -> Some function like this available? or i
        should write my own code?

        ...

          }

          
        Any pointers would help.

          
        Thank you,
