Hi all,
After merging the rcu tree, today's linux-next build (x86_64 allmodconfig)
failed like this:
In file included from include/linux/kernel.h:15,
from kernel/rcu/rcuscale.c:13:

Caused by commit
a20b5bd09813 ("rcuperf: Change rcuperf to rcuscale")
I have used the rcu tree from next-20200817 for today.
