As the title indicated, patchwork is creating new series items in its database when users reply to a particular patch. What it should be happening is that any reply should be considered as comment in patchwork and no series creation should be done. So far, I have found two examples: * series created on behalf on a 'ping' reply from the submitter: https://patchwork.openembedded.org/series/4578/ * new revision created on behalf of reply https://patchwork.openembedded.org/series/4506/#rev2
A patch that addresses both this and bug 10764 can be seen in: https://lists.yoctoproject.org/pipermail/yocto/2017-January/033835.html this is implemented for testing in the staging instance: https://patchwork-staging.openembedded.org/
This has been implemented in production patchwork: http://git.yoctoproject.org/cgit/cgit.cgi/patchwork/commit/?id=1a096ecdec71ad20e47af075e0126f77c54e7ec9
