Hi all,
After merging the rcu tree, today's linux-next build (x86_64 allmodconfig)
failed like this:
ERROR: modpost: "srcu_check_nmi_safety" [arch/x86/kvm/kvm.ko] undefined!
ERROR: modpost: "srcu_check_nmi_safety" [arch/x86/kvm/kvm-intel.ko] undefined!

WARNING: modpost: suppressed 10 unresolved symbol warnings because there were too many)
Presumably caused by commit
54a118fce487 ("srcu: Debug NMI safety even on archs that don't require it")
I have used the rcu tree from next-20221017 for today.
