Hi,
here's the new version of the patches to add subcluster allocation
support to qcow2.
Please refer to the cover letter of the first version for a full
description of the patches:
https://lists.gnu.org/archive/html/qemu-block/2019-10/msg00983.html
The big change here is that now when an image is preallocated then the
requested clusters are allocated but the L2 bitmap is left untouched.
This makes it possible to preallocate an image that has a backing
file.
If you want to test this series make sure to apply this patch first:

Let's spell that the way patchew can recognize:
