First it used for crash size. Then its meaning is changed to buffer size in ck_cmdline. And types are different too. The type for crash size is unsigned long long. But scnprintf() return int. Could you use two variables to represent the two meanings for less confusion?
Sure, OK, will do. Thanks. -- To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
