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: Linux 5.9-rc1 (2020-08-16 13:04:57 -0700) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git rcu/urgent for you to fetch changes up to 78edc005f477a4987ee0a5d96bfe117295c231fd: rcu-tasks: Prevent complaints of unused show_rcu_tasks_classic_gp_kthread() (2020-09-16 16:32:36 -0700) ---------------------------------------------------------------- Paul E.
