I'll look at it. Some naive questions: - do we have evidence that this is useful in its current form? - any advice on testing? Is there was some simple virtual setup that would allow any loser with no special hardware (e.g., me) to check whether they've broken the block server? - any debugging advice? E.g., have you checked if current wireshark can handle the MDS traffic? --b. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
