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.
