Subject: [PATCH 0/3] srcu: Fix boot stall
Date: Fri, 2 Apr 2021 01:47:01 +0200 [thread overview]
Message-ID: <20210401234704.125498-1-frederic@kernel.org> (raw)
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.

rcu/dev
HEAD: 6390b2aa1295f79150fac8f5ff60177eea5d8f8b
Thanks,
Frederic
