[PATCH v3 0/2] Toyrcu: replace plain accesses with READ_ONCE()

Junchang Wang <junchangwang@xxxxxxxxx> · Mon, 29 Apr 2019 22:38:42 +0800

Hi list,

Variable rcu_gp_ctr is accessed concurrently by the updater and readers,
and hence should be protected by READ_ONCE() and WRITE_ONCE(). This patch
set updates rcu and rcu_qs.

The tex file is updated accordingly. And a new scheme, which is suggested
by Akira and can extract code snippets from the source code, has been
applied.

Please note that rcu_nest also needs to be updated. I will first make sure
that I'm fully understand how it works, and then submit a patch for it.
