[PATCH 0/3] srcu: Fix boot stall
From: Frederic Weisbecker
Date: Thu Apr 01 2021 - 19:47:18 EST
This is a fix for a boot stall that can be reproduced with
"rcupdate.rcu_self_test=1" and CONFIG_PROVE_RCU=y.
It should be easy to trigger if you set CONFIG_MAXSMP=y and you don't
actually have thousands of CPUs.
