Nope, for the simple reason that we can't go back in time and add them to old releases :) > Is there some general policy regarding this or is it a question that I > need to ask the maintainer of the subsystem that the driver belongs > to? Have you read the stable_kernel_rules.txt file in the Documentation directory for what type of patch is allowed in the stable kernel releases? It should answer this question. Also look at the development_process/ "book" in the tree, that should help out. In short, you always have to add new features to the latest development verison of the kernel. hope this helps, greg k-h _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
