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.

rcu: Use READ_ONCE() and WRITE_ONCE() for shared variable rcu_gp_ctr
rcu_qs: Use READ_ONCE() AND WRITE_ONCE() for shared variable
rcu_gp_ctr
