If I understood correctly, this does cluster-level dedup within a qcow2 image. What is the motivation here? Reduce space usage if a guest copies files internally? Why use cluster granularity? If the guest uses smaller granularity, it will misalign the data wrt cluster boundaries, and deduplication will fail. -- error compiling committee.c: too many arguments to function
