It gets caught by the return into userspace code.
Specifically the signal dispatch should repair that return value to a valid error return code when it tries to dispatch the signal that select() set in the task struct.
Note that select() only returns these values when signal_pending() is true. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
