Subject: Assign task_struct.exit_code before taskstats_exit()
From: Jonathan Lim <jlim@xxxxxxx>
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().
