I think, amoung other things, we have some a nice language barrier here. I think, as I tried to explain, that you need to distinguish between what happens on the DRBD protocol level, and what happens on the communication transport level. The latter is what you are working on. You can do almost whatever you want there. But it should be obvious that you cannot re-use the DRBD protocol level "my-disk-has-failed-I-am-so-sorry" message to mean, on the transport layer, "please-resend-all-requests-I-did-miss", just because both concepts use the term "nack" somewhere in the description. Different things. Both needed.
