But.... If we never actually need fast access to the approximate total, (which seems to apply to this and the previous patch) we could use something much simpler which does not have the spinlock or all this batching stuff that percpu counters have. I'd prefer that because it will be faster in a straight line... (BTW. percpu counters can't be used in interrupt context? That's nice.) -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
