WalkthroughAdds OpenShift CSI capability overrides and a test suite that force-unmounts a CSI volume on the host, removes its directory, and verifies pod deletion. ChangesCSI pod deletion validation
Estimated code review effort: 3 (Moderate) | ~25 minutes Mergeability Score: 🔵 Low · up to The test setup may leave generated driver manifests behind when temporary-file cleanup fails, without surfacing the failure. The change is otherwise mergeable with explicit owner follow-up to propagate cleanup errors. Sequence Diagram(s)sequenceDiagram

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Use a forced unmount for this test scenario.
Line 98 uses normal umount. The suite contract requires validation after a force-unmount. This command can test a different cleanup path and leave the intended regression untested. Add -f.
Proposed fix
- err = hostExec.IssueCommand(ctx, fmt.Sprintf("umount %q && rmdir %q", mountPath, mountPath), node)
+ err = hostExec.IssueCommand(ctx, fmt.Sprintf("umount -f %q && rmdir %q", mountPath, mountPath), node)📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Handle temporary-file cleanup errors.
Line 155, Line 165, Line 166, and Line 170 discard errors from os.Remove or Close. A failed cleanup can leave generated manifests in the driver-manifest directory without reporting the failure.
Change the cleanup function to return an error. Propagate cleanup failures from AddDriverDefinition while preserving an external.AddDriverDefinition failure when both operations fail.
As per path instructions, **/*.go requires: “Never ignore error returns.”
