…325) * On **```cbo.clean```**, the ```WriteCleanFull``` was determined to be sent only when L1 returned dirty data or L2 contained dirty data. * Directory meta update was done only by ```mp_release``` on ```WriteCleanFull``` before for CMO operations. * When L2 contained clean record and L1 returned clean (```ProbeAck TtoB```), ```WriteCleanFull``` was unnecessary. While, the cache line state was still needed o be updated from ```TRUNK``` to ```TIP``` in L2. So ```mp_cmometaw``` was introduced for cache line state update compensation for ```ProbeAck TtoB```.
