Name:Send signals to all our closest relatives so that they know* to properly mourn us..

Proto:static void exit_notify(struct task_struct *tsk, int group_dead)

Type:void

Parameter:

Type	Parameter	Name
struct task_struct *	tsk
int	group_dead

649

LIST_HEAD(dead)

651

write_lock_irq( & tasklist_lock)

652

This does two things:* A. Make init inherit all the child processes* B. Check to see if any process groups have become orphaned* as a result of our exiting, and if they have any stopped* jobs, send them a SIGHUP and then a SIGCONT. (POSIX 3.2.2.2)

654

If group_dead Then Check to see if any process groups have become orphaned as* a result of our exiting, and if they have any stopped jobs,* send them a SIGHUP and then a SIGCONT. (POSIX 3.2.2.2)

657

exit state = EXIT_ZOMBIE

658

If Value for the false possibility is greater at compile time(ptrace) Then

659

sig = If thread_group_leader(tsk) && thread_group_empty(tsk) && Not ptrace_reparented(tsk) Then exit signal Else SIGCHLD

663

autoreap = do_notify_parent(tsk, sig)

664

Else if thread_group_leader(tsk) Then

665

autoreap = thread_group_empty(tsk) && do_notify_parent(tsk, exit signal)

667

Else

668

autoreap = true

671

If autoreap Then

672

exit state = Used in tsk->exit_state:

673

list_add - add a new entry*@new: new entry to be added*@head: list head to add it after* Insert a new entry after the specified head.* This is good for implementing stacks.

677

If Value for the false possibility is greater at compile time(notify_count < 0) Then wake_up_process(group_exit_task)

679

write_unlock_irq( & tasklist_lock)

682

list_del_init - deletes entry from list and reinitialize it.*@entry: the element to delete from the list.
