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).
Leonid Bloch (4):

image
docs: Fix an inaccuracy due to recent changes
docs: Document the l2-cache-full option
