I was not sure so I extended the > check to > if ((val != -ERESTARTSYS) && (val > 0)) I changed the check to just "val > 0". The comments in the kernel around the implementation and declaration of the function wait_event_interruptible() VERY CLEARLY state that the possible return values are: 1) Negative error code on interrupt 2) Zero if timeout expired 3) Positive non-zero value if condition became true before timeout expired So there is no doubt that "val > 0" is sufficient. - To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
