Yeah, right, good catch.

Because in this case if group_exit_code is null, we want
tsk->exit_code, not 0.

Andrew is not interested at the moment in this series (that replaces
all my previous patches on taskstats, for info), but thank you for the
review.

Isn't this just confusing? why not
if (tg_stats) {
group_exit_code = tsk->signal->group_exit_code;
stats->ac_exitcode = group_exit_code;
} else {
group_exit_code = 0;
stats->ac_exitcode = tsk->exit_code;
