Oleg Nesterov 7c8bd2322c exit: ptrace: shift "reap dead" code from exit_ptrace() to forget_original_parent() ... Now that forget_original_parent() uses ->ptrace_entry for EXIT_DEAD tasks, we can simply pass "dead_children" list to exit_ptrace() and remove another release_task() loop. Plus this way we do not need to drop and reacquire tasklist_lock. Also shift the list_empty(ptraced) check, if we want this optimization it makes sense to eliminate the function call altogether.
