From 8a15b813e6034856d4177c6ab242791795434c15 Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Mon, 17 Mar 2014 23:04:51 +0100 Subject: [PATCH] qcow2: Correct comment for realloc_refcount_block() 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.
