This is the only commit involving kernel/rcu/typesafe.o, so...
One the one hand, I do not plan to upstream this, so maybe it doesn't
matter.
I have been building this using the rcutorture scripting for some time,
same RCU-related .config as you are using. But when I pulled it into
a clone in a neighboring directory, it failed just as it did for you.
The problem was that the update to kernel/rcu/Makefile somehow didn't
come across, so this line was missing:
obj-$(CONFIG_RCU_TYPESAFE_TEST) += typesafe.o
Which of course explains the build failure.
I blew away that clone and re-cloned it. And it still failed, both
with "make" from the commandline and under rcutorture.
Hahahahahahaahaha!!!
I forgot "git add kernel/rcu/typesafe.c".
There is now a new typesafe.2022.02.21a tag with this file added.
Good catch! That file happened to still be lying around. The first
"git reset --hard" would have destroyed. Thank you!!!
And with that fixed, my clone now builds correctly. Does this fix
it for you?
Thanx, Paul

Hi Paul,
I can't find the tag 'typesafe.2022.02.21a' from
https://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git/refs/tags

That would be because I failed to push it out. :-/
Which I just now did, apologies for my confusion.
