If we use walltime there's no guarantee that the clock is correct and if we use local_clock() (my preference) it will be reset after every boot. I just think using something like UUID is more robust. Especially if one implements an automatic crash dump collector from thousands of deployed APs, having an UUID makes it a lot easier to manage. -- Kalle Valo -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
