Commit 8344496e8b49 ("rcu-tasks: Conditionally compile show_rcu_tasks_gp_kthreads()") introduced conditional compilation of several functions, but forgot one occurrence of show_rcu_tasks_classic_gp_kthread() that causes the compiler to warn of an unused static function. This commit uses "static inline" to avoid these complaints and possibly also to avoid emitting an actual definition of this function.
