Review Comment:
   > Thanks @siddhantsangwan for sharing the rationale, makes sense. I agree 
about the need to avoid unnecessary object creation (StorageLocationReport). I 
think trying to avoid a simple method call (to VolumeUsage) is unnecessary, but 
is OK for now. I can continue refactoring later and ask you to review. :)
   
   Sounds good!
   
   > Since there is a merge conflict anyway, I'd like to ask you to make 
another small change by swapping the order of || here:
   
   Ah, that's a good suggestion, will push it along with the conflict 
resolution.
