NAME
       tracehook_notify_death - task is dead, ready to notify parent

SYNOPSIS
       int tracehook_notify_death(struct task_struct * task, void ** death_cookie, int group_dead);

ARGUMENTS
       task

	   current task now exiting

       death_cookie
	   value to pass to tracehook_report_death

       group_dead
	   nonzero if this was the last thread in the group to die

DESCRIPTION
       A return value >= 0 means call do_notify_parent with that signal number. Negative return value can be DEATH_REAP to self-reap right now, or
       DEATH_DELAYED_GROUP_LEADER to a zombie without notifying our parent. Note that a return value of 0 means a do_notify_parent call that sends
       no signal, but still wakes up a parent blocked in wait*().

       Called with write_lock_irq(tasklist_lock) held.
