The documentation in sched.h:1313 says that "parent" refers to the
parent task that would receive SIGCHLD (i.e., the one that issues
wait4()). ?I followed the wait4() syscall to do_wait(), I still am not
able to find where the task's parent is updated.

I am bit rusty here, but AFAIK sigchld is thrown to the process who
ptrace another process. CMIIW
