Hi Balbir,

That was what I wanted to do at first, but there was some concern over whether
it would affect any of the intervening function calls. If there's no
particular reason why the tsk->exit_code assignment is placed where it's at
now, then yes, I would much rather move it to before taskstats_exit().

I looked at the following functions involving tsk:


and don't see anything that setting exit_code would affect. What do you think?
