I forgot to replace "kernel_cpu_shader" -> "shader_function" :(

You can submit a new diff, and after upload you can attach it to this revision, instead of creating a new revision. :)

You can click on "Submit Code" on the frontage (developer.blender.org), then upload the diff there and press "Create diff". In the next step you select this revision here from the drop down menu. ;) That's what I meant.

Generally the idea is fine. But do you mind updating the patch so it applies on top of current master? Would help a lot committing it.

I created a path, but I now have no possibility to compile for checking
