For the parts of the drm subsystem that follow the maintainer/committer model, the Link: trailer is also part of an audit trail, if you will, that only patches actually posted on the list get committed and pushed. "Something like this was once posted somewhere" is nowhere near the same as "this is the exact patch, as part of this series". For i915 and xe, you'll additionally find the CI results for the exact patch/series, and passing result is part of the merge criteria. BR, Jani. -- Jani Nikula, Intel
