From c84087f2f52f6e87ad1cbd07e5502ab748c17039 Mon Sep 17 00:00:00 2001 From: Vladimir Sementsov-Ogievskiy Date: Fri, 2 Jun 2017 18:01:46 +0300 Subject: nbd/server: remove NBDClientNewData "co" field of NBDClientNewData has never been used, all the way back to its declaration in commit 1a6245a5. So let's just use client pointer instead of extra structure.
