linux-next: build failure after merge of the rcu tree

[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi all,

After merging the rcu tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

kernel/rcu/rcuscale.c:340:27: error: 'get_rcu_tasks_trace_gp_kthread' undeclared here (not in a function); did you mean 'show_rcu_tasks_trace_gp_kthread'?
  340 |         .rso_gp_kthread = get_rcu_tasks_trace_gp_kthread,
      |                           ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      |                           show_rcu_tasks_trace_gp_kthread

Caused by commit

  9bb839a83e1b ("rcuscale: Measure grace-period kthread CPU time")

CONFIG_RCU_SCALE_TEST=m

I have used the rcu tree from next-20230518 for today.
