This is a very confusing patch submission.

You're posting a "v2" of a patch but with a completely different Subject
line so that it's hard, without looking into the details of the patch,
to determine what this patch is a "v2" of.

You've also not addressed Stephen's feedback about the lack of an
rcu_dereference() in these routines you've added __rcu annotations
to.

I'm tossing all versions of this patch, therefore.
