From ae5475e82fd1ebb24f4f77cf28f59ca6548c6136 Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Tue, 26 Jun 2018 13:22:45 +0200 Subject: [PATCH] qcow2: Fix qcow2_truncate() error return value If qcow2_alloc_clusters_at() returns an error, we do need to negate it to get back the positive errno code for error_setg_errno(), but we still need to return the negative error code.
