### 6.1 Modifying Smb2CreateRequest
```java
// In Smb2CreateRequest.java
public void addLeaseContext(Smb2LeaseKey key, int requestedState, boolean isV2) {
    Smb2LeaseContext leaseContext = new Smb2LeaseContext();
    leaseContext.setLeaseKey(key);
    leaseContext.setLeaseState(requestedState);
    if (isV2) {
        leaseContext.setEpoch(1);
        // Set parent lease key if available
    }

}
```

## 4. Data Structures

### 4.1 Directory Lease Context
```java
package jcifs.internal.smb2.lease;

public class DirectoryLeaseContext extends Smb2LeaseContext {
    public static final String NAME_DIRECTORY_REQUEST = "DLse";
    public static final String NAME_DIRECTORY_RESPONSE = "DLse";
    
    private DirectoryCacheScope cacheScope;
    private long maxCacheAge;
