From: Vladimir Sementsov-Ogievskiy Date: Fri, 7 Jul 2017 15:29:10 +0000 (+0300) Subject: nbd/server: refactor nbd_negotiate X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=76ff081d91d215a4f91849653bdc2ebd8f657183;p=qemu.git nbd/server: refactor nbd_negotiate Combine two successive "if (oldStyle) {...} else {...}" into one. Block "if (client->tlscreds)" under "if (oldStyle)" is unreachable, as we have "oldStyle = client->exp != NULL && !client->tlscreds;". So, delete this block.
