We do not add code to the kernel for out of tree code, sorry. To do so would be a total nightmare and maintance impossiblity, and not something you would want us to do as Linux overall would suffer. As you well know, the correct solution is to get your code merged upstream. I have asked many times to get the gasket code upstream properly, please do so to resolve problems like this. thanks, greg k-h
