This bug happens when running the rcuscale and refscale tests, not the
usual rcu, lock, and scf torture tests. So I would catch it only if
I ran my overnight torture-everything test against -next during the
critical time, which I failed to do this time. :-/

My guess is that others building such kernels don't often test against
-next.

For whatever it is worth, here is my overnight torture-everything test,
which takes about 15 hours on a 16-CPU system:

./tools/testing/selftests/rcutorture/bin/torture.sh --duration 10 --do-kcsan --kcsan-kmake-arg "CC=clang-11"

Thank you!
