The /backport commit command and /backport pull request command can be used to quickly create a backport pull request for a given commit. Just navigate to the original commit or pull request in source code hosting provider's web UI and add a comment consisting of
/backport <repo> [<branch>]. If the commit does not apply clean on the target repository then a message will be shown for the files with conflicts.
The pull request will be created from a branch in a shared fork of the target repository. On GitHub, this repository is owned by the openjdk-bots organization. The first time you issue the /backport command for a specific target repository, you will receive an invitation to collaborate in this the fork repository. This invitation needs to be accepted to be able to further update the backport pull request with more changes.
Navigate the to commit intended to be backported in the source code hosting provider's web UI and issue the /backport commit command. If the commit applied cleanly onto the target repository then go to the pull request linked in the reply and issue the /integrate pull request command.
