Re: [PATCH v4 09/15] rcu: convert process/thread iterator to for_each_process_thread_rculock

From: Ye Liu <liuye@kylinos.cn>

Replace the manual rcu_read_lock()/rcu_read_unlock() pair combined
with for_each_process_thread() loop in kernel/rcu/update.c with
for_each_process_thread_rculock(), which scopes the RCU read lock
to the loop body via scoped_guard(rcu).

No functional change.
