hi, i want to implement the function of qcow2 resize which has snapshots. each snapshot of qcow2 will have a separate total size, and when apply a snapshot,
the image can be shrunk, and the total size of image will change after apply to a snapshot with different size. now, there is a disk_size value in struct QcowSnapshot, i only need to change the size of current active image layer when apply a snapshot with different size, and the io request will be limit in the range of active layer. and i want my code merged into the master of qemu. please give me some comments. thanks. zhangzhiming zhangzhiming...@163.com
