Subject: [GIT RFC PULL rcu/urgent] Fix rcu-tasks compilation warning

Hello!

This pull request contains a single commit that fixes a bug that
was introduced in the last merge window.  This bug causes a compiler
warning complaining about show_rcu_tasks_classic_gp_kthread() being an
unused static function in !SMP kernels.  The fix is straightforward,
just adding an "inline" to make this a static inline function, thus
avoiding the warning.  This bug was reported by Laurent Pinchart (CCed),
who would like it fixed sooner rather than later.  So:

The following changes since commit 9123e3a74ec7b934a4a099e98af6a61c2f80bbf5:
