w1_therm_read_bin: suspicious usage of flush_signals()

[Oleg Nesterov]

drivers/w1/slaves/w1_therm.c:w1_therm_read_bin()

	while (tm) {
		tm = msleep_interruptible(tm);
		if (signal_pending(current))
			flush_signals(current);
	}

current is user-space task, yes?

this looks just wrong, could you please explain?

Oleg.
