If you start reformmating it please get it completely right:

	if (info == SEND_SIG_NOINFO ||
	    (!is_si_special(info) && SI_FROMUSER(info))) {
		/* Let audit system see the signal */
		error = audit_signal_info(sig, t);
 		if (error)
 			return error;
 		error = -EPERM;
		if ((sig != SIGCONT ||
		     (task_session_nr(current) != task_session_nr(t))) &&
		    (current->euid ^ t->suid) && (current->euid ^ t->uid) &&
		    (current->uid ^ t->suid) && (current->uid ^ t->uid) &&
		    !capable(CAP_KILL))
			return error;
 	}
