[Qemu-devel] [PATCH] block: Create proper size file for disk mirror

The qmp monitor command to mirror a disk was passing -1 for size along with the disk's backing file. This size of the resulting disk is the size of the backing file, which is incorrect if the disk has been resized. Therefore we should always pass in the size of the current disk. Signed-off-by: Vis
