No, commit e356d321d024 ("drm/amdgpu: cleanup MES11 command submission") is in the 6.10 release, but commit de3246254156 ("drm/amdgpu: cleanup MES11 command submission") is in 6.11-rc1! So how in the world are we supposed to know anything here? See how broken this all is? I give up. If you all want any AMD patches applied to stable trees, manually send us a set of backported patches, AND be sure to get the git ids right. I'll leave what I have right now in the queues, but after this round of -rc releases, all AMD patches with cc: stable are going to be automatically dropped and ignored. I NEED you all to manually send them to me now as this is just insane. Time to go buy a Intel gpu card as there's no way this is going to work out well over time... {sigh} greg k-h
