Please scream at me if I messed something up. Please test the patches too. The -rc release will be uploaded to kernel.org and will be deleted when the final release is out. This is just a review release (or release candidate). The pre-releases will not be pushed to the git repository, only the final release is. If all goes well, this patch will be converted to the next main release on 1/24/2020.
