> I want to add a rule *'The quota should be set the same as the nearest
> parent'* to Global Quota. Supposing we have the mount table below.
> M1: /dir-a ns0->/dir-a \{nquota=10,squota=20}
> M2: /dir-a/dir-b ns1->/dir-b \{nquota=-1,squota=30}
> M3: /dir-a/dir-b/dir-c ns2->/dir-c \{nquota=-1,squota=-1}
> M4: /dir-d ns3->/dir-d \{nquota=-1,squota=-1}
>
> The quota for the remote locations on the namespaces should be:
> ns0->/dir-a \{nquota=10,squota=20}
> ns1->/dir-b \{nquota=10,squota=30}
> ns2->/dir-c \{nquota=10,squota=30}
> ns3->/dir-d \{nquota=-1,squota=-1}
>
> The quota of the remote location is set the same as the corresponding
> MountTable, and if there is no quota of the MountTable then the quota is set
> to the nearest parent MountTable with quota.
>
> It's easy to implement it. In RouterQuotaUpdateService each time we compute
> the currentQuotaUsage, we can get the quota info for each MountTable. We can
> do a
> check and fix all the MountTable which's quota doesn't match the rule above.
