Well, the idea would be something like: NBD_CMD_INFO, use the offset specified as the the information type, and put the INFO reply within the reply block. I guess the client doesn't know the length of the reply so we'd have to use structured replies or similar. Although looking through the current info types, I can't see why today you'd want to reread anything other than the length, so maybe this is useless futureproofing. -- Alex Bligh
