* opened if it is not and should be closed with {@link #close()} when no longer
     * needed.
     *
     * Closing the context should cancel a pending notify request, but that does not seem to work reliable in all
     * implementations.
     *
     * Changes in between these calls (as long as the file is open) are buffered by the server, so iteratively calling

### Technical Risks
1. **RDMA Complexity**: Limited Java RDMA support may require JNI
2. **Multi-Channel Synchronization**: Complex thread synchronization required
3. **Persistent Handle State**: Requires reliable state persistence mechanism
4. **Backward Compatibility**: Must maintain compatibility with SMB2/SMB1

### Mitigation Strategies
1. Implement features behind configuration flags
2. Provide graceful fallback mechanisms

- **MS-SMB2 Section 3.1.5.2**: RDMA Transport Connection
- **RFC 5040**: A Remote Direct Memory Access Protocol Specification
- **RFC 5041**: Direct Data Placement over Reliable Transports

## 3. RDMA Architecture

### 3.1 RDMA Capabilities
```java
public enum RdmaCapability {
    RDMA_READ,           // Remote direct read operations

                info = response;
                fileSize = response.getDataSize();

                // this is so damn unreliable, needs another race-prone query if required
                haveAttributes = false;

                // This seems to be the only way to obtain a reliable (with respect to locking) file size here
                // It is more critical than other attributes because append mode depends on it.
