- Pass additional flags to subpath mount to avoid flakes in certain conditions ([#104347](https://github.com/kubernetes/kubernetes/pull/104347), [@mauriciopoppe](https://github.com/mauriciopoppe)) [SIG Storage]

- E2e.test: removed the  `--viper-config` flag. If you were previously using this to pass flags to `e2e.test` via a file, you will need to pass them directly on the command line, e.g. `e2e.test --e2e-output-dir`.

- `(*"k8s.io/client-go/rest".Request).{Do,DoRaw,Stream,Watch}` now require callers to pass a `context.Context` as an argument. The context is used for timeout and cancellation signaling and to pass supplementary information to round trippers in the wrapped transport chain. If you don't need any of this functionality, it is sufficient to pass a context created with `context.Background()` to these functions. The `(*"k8s.io/client-go/rest".Request).Context` method...
