[Qemu-devel] [PATCH for-4.0 1/3] block: continue until base is found in bdrv_freeze_backing_chain() et al

All three functions that handle the BdrvChild.frozen attribute walk the backing chain from 'bs' to 'base' and stop either when 'base' is found or at the end of the chain if 'base' is NULL. However if 'base' is not found then the functions return without errors as if it was NULL. This is wrong: if

If qemu-img convert sees that the target image isn't zero-initialised yet, it tries to do an efficient zero write for the whole image first to save the overhead of repeated explicit zero writes during the conversion.
