This series introduces an option to calculate and allocate
automatically enough qcow2 L2 cache to cover the entire image.
Using cache that covers the entire image can benefit performance,
while having only a small memory overhead (just 1 MB for every 8 GB
of virtual image size with the default cluster size).

Is this still needed after Berto's work on commit 603790e and related, that maximizes the l2 cache by minimizing the refcount cache?
