taskstats.ac_exitcode is assigned to task_struct.exit_code in bacct_add_tsk() through the following kernel function calls:
do_exit() taskstats_exit() fill_pid() bacct_add_tsk()
The problem is that in do_exit(), task_struct.exit_code is set to 'code' only after taskstats_exit() has been called. So we need to move the assignment before taskstats_exit().
