This series makes the qcow2 L2 cache cover the entire image by default.
The importance of this change is in noticeable performance improvement,
especially with heavy random I/O. The memory overhead is very small:
only 1 MB of cache for every 8 GB of image size. On systems with very
limited RAM the maximal cache size can be limited by the existing
cache-size and l2-cache-size options.
The L2 cache is also resized accordingly, by default, if the image is
resized.
Are you going to send a new version that makes the changes we agreed on?
