KOSAKI Motohiro 9b1bf12d5d signals: move cred_guard_mutex from task_struct to signal_struct ... Oleg Nesterov pointed out we have to prevent multiple-threads-inside-exec itself and we can reuse ->cred_guard_mutex for it. Yes, concurrent execve() has no worth. Let's move ->cred_guard_mutex from task_struct to signal_struct. It naturally prevent multiple-threads-inside-exec.
