[v2.1.1] Release Tracker
Labels: triaged

### 🐛 Describe the bug

This issue is for tracking cherry-picks to the release branch. Following is [release branch](https://github.com/pytorch/pytorch/tree/release/2.1) for the 2.1.1 release.

Our plan from this point from this point is roughly:

* Phase 1 (until 11/3): Cherry-pick post deadline (End of day 5PM PST)
* Phase 2 (after 11/3):  Perform extended integration/stability/performance testing based on Release Candidate builds.

**Only issues that have ‘cherry-picks’ in this tracker will be considered for the release.**

## Cherry-Pick Criteria

**Phase 1 (until 11/3):**

The Releng team relies on the cherry pick process to manage risk to release quality, i.e. by porting a small set of commit from trunk that are "must-have" into the release branch, we limit the change to the minimal to address pressing issues. Thus, not everything a developer land into the trunk will make it into the release. So, please consider the criteria below and follow the cherry picking process. Only low-risk changes may be cherry-picked from master:

1. Fixes to regressions against the most recent release (e.g. 2.1.0 for 2.1.1 release; see [module: regression issue list](https://github.com/pytorch/pytorch/issues?q=is%3Aissue+is%3Aopen+label%3A%22module%3A+regression%22+))
2. Low risk critical fixes for: silent correctness, backwards compatibility, crashes, deadlocks, (large) memory leaks
3. Fixes to new features being introduced in 2.1.0 release
4. Documentation improvements
5. Release branch specific changes (e.g. blocking ci fixes, change version identifiers)


Any other change requires special dispensation from the release managers (currently @atalman, @huydhn, @osalpekar, @malfet). If this applies to your change please write "Special Dispensation" in the "Criteria Category:" template below and explain. 

**Phase 2 (after 11/3):**

Note that changes here require us to rebuild a Release Candidate and restart extended testing (likely delaying the release). Therefore, the only accepted changes are **Release-blocking** critical fixes for: [silent correctness](https://github.com/pytorch/pytorch/issues?q=is%3Aissue+is%3Aopen+label%3A%22topic%3A+correctness+%28silent%29%22), [backwards compatibility](https://github.com/pytorch/pytorch/issues?q=is%3Aissue+is%3Aopen+label%3A%22topic%3A+bc-breaking%22+), [crashes](https://github.com/pytorch/pytorch/issues?q=is%3Aissue+is%3Aopen+label%3A%22topic%3A+crash%22+), [deadlocks](https://github.com/pytorch/pytorch/issues?q=is%3Aissue+is%3Aopen+label%3A%22topic%3A+deadlock%22+), (large) [memory leaks](https://github.com/pytorch/pytorch/issues?q=is%3Aissue+is%3Aopen+label%3A%22topic%3A+memory+usage%22+)

Changes will likely require a discussion with the larger release team over VC or Slack.

## Cherry-Pick Process

1. Ensure your PR has landed in master. This does not apply for release-branch specific changes (see Phase 1 criteria).
2. Create (but do not land) a PR against the [release branch](https://github.com/pytorch/pytorch/tree/release/2.0).
   <details>

    ```bash
    # Find the hash of the commit you want to cherry pick
    # (for example, abcdef12345)
    git log

    git fetch origin release/2.1
    git checkout release/2.1
    git cherry-pick abcdef12345

    # Submit a PR based against 'release/2.1' either:
    # via the GitHub UI
    git push my-fork

    # via the GitHub CLI
    gh pr create --base release/2.1
    ```

    </details>
3. Make a request below with the following format:

```
Link to landed master PR (if applicable):
* 

Link to release branch PR:
* 

Criteria Category:
* 
```

1. Someone from the release team will reply with approved / denied or ask for more information.
2. If approved, someone from the release team will merge your PR once the tests pass. **Do not land the release branch PR yourself.**

**NOTE: Our normal tools (ghstack / ghimport, etc.) do not work on the release branch.**
