XDP sockets use the default implementation of struct sock's sk_data_ready callback, which is sock_def_readable(). This function is called in the XDP socket fast-path, and involves a retpoline. By letting sock_def_readable() have external linkage, and being called directly, the retpoline can be avoided.
