Ack. That does look fishy. Almost anything else can probably be
unioned together with the rcu list, but *not* the refcount that we
might want to look at during the rcu grace period.

Al, this is your code (from long long ago). Want to take it through
the vfs tree, or should I just apply direectly? I'd like to have your
ack regardless, but the fix looks ObviouslyCorrect(tm) to me.
