[Qemu-devel] [PATCH v2 0/2] Introduction of l2-cache-full option for qcow2 images |

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).
-------------------------
Differences from v1:
1) Documentation fixes in qapi/block-core.json and qemu-options.hx
2) Removal of the patch which was made to fix the default sizes in
docs/qcow2-cache.txt - it is not needed, as the default sizes imply
also default cluster sizes.
3) Documentation fixes in docs/qcow2-cache.txt, mentioning mutual
exclusivity of the options.
4) Squashing the iotests patch into the main feature addition patch
