[PATCH v7 08/32] qcow2: Add dummy has_subclusters() function |
Date: |
Mon, 25 May 2020 20:08:33 +0200 |
This function will be used by the qcow2 code to check if an image has
subclusters or not.
At the moment this simply returns false. Once all patches needed for
subcluster support are ready then QEMU will be able to create and
read images with subclusters and this function will return the actual
value.
