#     Merge branch 'rcu/urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu
#     
#     Pull RCU fix from Paul McKenney:
#      "This 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, who would like it fixed
#       sooner rather than later"
#

#       rcu-tasks: Prevent complaints of unused show_rcu_tasks_classic_gp_kthread()
