You're just adding a new function without any callers. This would be dead code. We don't generally commit dead code except as part of a series where a later patch makes use of it. Either way, since you just seem to print allocation status to stdout, maybe 'qemu-img map' is actually the right tool for what you are trying to do? Kevin
