From 96c80b0431925b725cb57ffa7a0f9ee29bfd973c Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Fri, 2 May 2014 16:58:55 -0500 Subject: [PATCH 23/26] qcow2: Correct comment for realloc_refcount_block() RH-Author: Max Reitz Message-id: <1399049936-13496-24-git-send-email-mreitz@redhat.com> Patchwork-id: 58667 O-Subject: [RHEL-6.6 qemu-kvm PATCH v3 23/24] qcow2: Correct comment for realloc_refcount_block() Bugzilla: 1004420 RH-Acked-by: Laszlo Ersek RH-Acked-by: Kevin Wolf RH-Acked-by: Stefan Hajnoczi BZ: 1004420 Contrary to the comment describing this function's behavior, it does not return 0 on success, but rather the offset of the newly allocated cluster. This patch adjusts the comment accordingly to reflect the actual behavior.
