def symlink_force(target, link_name):

the target, the DeleteMarker on the target shows `X-Amz-Replication-Status` of `REPLICA`. The status of DeleteMarker replication is returned by `X-Minio-Replication-DeleteMarker-Status` header on `HEAD/GET` calls for the delete marker version in question - i.e with `mc stat --version-id dm-version-id`

It must be noted that if active-active replication is set up with delete marker replication, there is potential for duplicate delete markers to be created if both source and target concurrently...

discussion, and please direct specific questions to
[Stack Overflow](https://stackoverflow.com/questions/tagged/tensorflow).**

The TensorFlow project strives to abide by generally accepted best practices in
open-source software development.

For any non-trivial change, we need to be able to answer these questions:

* Why is this change done? What's the use case?
* For user-facing features, what will the API look like?
* What test cases should it have? What could go wrong?
* How will it roughly be implemented? We'll happily provide code pointers to save you time.

We may ask you to answer these questions directly in the GitHub issue or (for large changes) in a shared Google Doc.
