Subject: Re: [PATCH 2/6] rcu: Create rcu_sync infrastructure

OK, so this is a real nit, but...in the changelog:

>         static inline void rcu_sync_enter(struct rcu_sync_struct *xxx)
>         {
>                 atomic_inc(&xxx->counter);
>                 synchronize_sched();
>         }
> 
>         static inline void rcu_sync_enter(struct rcu_sync_struct *xxx)
>         {
>                 synchronize_sched();
>                 atomic_dec(&xxx->counter);
>         }

That second rcu_sync_enter should really be rcu_sync_exit.

Is the "xxx" there to test spamassassin configurations? :)
