From 4057a2b24a5f5dae826d438217f77332c3a6842e Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Mon, 27 Oct 2014 11:12:53 +0100 Subject: block/qcow2: Implement status CB for amend MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The only really time-consuming operation potentially performed by qcow2_amend_options() is zero cluster expansion when downgrading qcow2 images from compat=1.1 to compat=0.10, so report status of that operation and that operation only through the status CB. For this, approximate the progress as the number of L1 entries visited during the operation.
