Doesn't this one needs to be changed too?

By the way, the code currently reads:

int d_validate(struct dentry *dentry, struct dentry *parent)
{
[...]
        rcu_read_lock();
        hlist_for_each_entry_rcu(d, node, head, d_hash) {
                if (d == dentry) {
                        dget(dentry);
                        return 1;
                }
        }
        rcu_read_unlock();
        return 0;
}

I know nothing about rcu_read_lock(), but why is there no
rcu_read_unlock() before the "return 1" case?
