Oleg Nesterov abdba6e9ea proc: task_state: ptrace_parent() doesn't need pid_alive() check ... p->ptrace != 0 means that release_task(p) was not called, so pid_alive() buys nothing and we can remove this check. Other callers already use it directly without additional checks. Note: with or without this patch ptrace_parent() can return the pointer to the freed task, this will be explained/fixed later.
