Hi all,

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

In file included from kernel/rcu/tree.c:5031:
kernel/rcu/tree_nocb.h: In function 'rcu_init_nohz':
kernel/rcu/tree_nocb.h:1162:14: error: 'rcu_nocb_is_setup' undeclared (first use in this function); did you mean 'rcu_nocb_setup'?
1162 | if (!rcu_nocb_is_setup) {
| ^~~~~~~~~~~~~~~~~
| rcu_nocb_setup
kernel/rcu/tree_nocb.h:1162:14: note: each undeclared identifier is reported only once for each function it appears in

Caused by commit

d6932dca19b1 ("rcu/nocb: Add an option to offload all CPUs on boot")

interacting with commit

8d2aaa9b7c29 ("rcu/nocb: Move rcu_nocb_is_setup to rcu_state")

I have used the rcu tree from next-20220414 for today.
