Good point! Would you like to submit a patch?
Some usages of RCU in the kernel code

Well, I actually raised 2 points and I'm not sure which one is the good one...
Could you please clarify ?
To answer your question, I don't have any problems for submitting a patch.
PS: This interface is pretty hard for discussing on an article. It's like bottom-posting
except we loose all its advantages... Just my 2 cents.

I was inviting a patch for incorporating the smp_wmb() into the rcu_assign_pointer.
The lock acquisition makes rcu_dereference() unnecessary, but cannot enforce the ordering
provided by the smp_wmb()/rcu_assign_pointer().
