+# Backporting preference for EXPORT_SYMBOL_GPL() and proprietary drivers
+This framework was designed by intent since its inception *only* for upstream
+Linux kernel drivers to avoid excuses about the difficulty to support upstream
+Linux kernel development while also supporting users on older kernels. To
+ensure the intent is respected currently all symbols that we do work on to
+backport are exported via EXPORT_SYMBOL_GPL() as we do work to backport them
+for the supported kernels. By using EXPORT_SYMBOL_GPL() we make it *clear* that
+if you use the backported symbols your software *is* considered derivative
+works of the Linux kernel.
