Imagine you have a system that gets two OOPs, followed by a full panic - but that the persistent store only has space for two of the three reports. I think that most people would want the first OOPs and the panic ... i.e. drop the middle bit, rather than the oldest bit. -Tony -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
