The rtort_pipe_count WARN() indicates that grace periods were unable to invoke all callbacks during a stutter_wait() interval. But it is sometimes helpful to have a bit more information as to why. This commit therefore invokes show_rcu_gp_kthreads() immediately before that WARN() in order to dump out some relevant information. Signed-off-by: Paul E.
