> 1. FileWithSnapshot#updateQuotaAndCollectBlocks did not consider the scenario
> that all the snapshots has been deleted from a snapshot copy of deleted file.
> This may lead to a divide-by-0 error.
> 2. When computing the quota usage for a WithName node and its subtree, if the
> snapshot associated with the WithName node at the time of rename operation
> has been deleted, we should compute the quota based on the posterior snapshot.
