This is made all the more clear when I'm editing the response in vim that doesn't even show the mail subject to me.

Which leads to... I disagree. Without knowing what exactly is fixed how can you judge whether the patch even makes sense? And later you may get another report of the same warning and then you would want to look through the git log to see if there's a patch that already fixed it. Quite hard to do without the exact warning in the log. -- Ville Syrjälä Intel _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
