#### 5.2 Implementation Tasks
- [ ] Research Java RDMA libraries (e.g., DiSNI, JXIO)
- [ ] Implement RDMA capability detection
- [ ] Create RDMA negotiation context
- [ ] Implement RDMA transport layer

    try {
        super.close();
    } finally {
        // Don't release directory lease on close - it may be shared
        // Lease will be cleaned up by the lease manager
    }
}
```

### 5.2 Session Integration
```java
// In SmbSession.java
private DirectoryLeaseManager directoryLeaseManager;

public void initializeDirectoryLeasing() {

        if (provider.isAvailable()) {
            log.info("Selected RDMA provider: {}", provider.getProviderName());
            return provider;
        }
    }
    
    return null;
}
```

### 5.2 SMB2 Read/Write with RDMA
