From ba8456442b597848fb5585273c47de8476c3a0c1 Mon Sep 17 00:00:00 2001 From: Vladimir Sementsov-Ogievskiy Date: Fri, 4 Aug 2017 18:14:26 +0300 Subject: nbd/client: refactor nbd_receive_reply Refactor nbd_receive_reply to return 1 on success, 0 on eof, when no data was read and <0 for other cases, because returned size of read data is not actually used.
