Hi,
I am reading the code of merge() function in image.py and get one
question about the code. I wonder why we should get the volume
parameters from the parent of the destination volume if the parent is
existing instead from the destination volume itself?
1101 if dstParentUUID != sd.BLANK_UUID:
volParams = vols[dstParentUUID].getVolumeParams()
else:
1105 volParams = dstVol.getVolumeParams()
In my understanding, the volParams is different in internal volume
merge and base volume merge(merging to a top most base without parent).
For internal volume merge, the volParams comes from the parent of the
destination volume. While for base volume merge, the volParams comes
from the destination volume. Is it correct?
