From 148da7ea9d66bad0d5b6512074fbedc4e2640e8f Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Wed, 20 Jan 2010 15:03:01 +0100 Subject: qcow2: Return 0/-errno in qcow2_alloc_cluster_offset Returning 0/-errno allows it to distingush different errors classes. The cluster offset of newly allocated clusters is now returned in the QCowL2Meta struct.
