> Not all callers of INodeFile#getBlocks check for null. e.g.
> {code}
> public final QuotaCounts storagespaceConsumedContiguous(
> BlockStoragePolicy bsp) {
> ...
> // Collect all distinct blocks
> Set<BlockInfo> allBlocks = new HashSet<>(Arrays.asList(getBlocks()));
> {code}
> We can either fix each caller or alternatively fix getBlocks to never return
> null.
