Dmitry, your email client chopped up the longer lines in the patch
such as:
> -static inline int sk_filter(struct sock *sk, struct sk_buff *skb, int
> needlock)
> +static inline int sk_filter(struct sock *sk, struct sk_buff *skb)
Here.
> -static inline unsigned run_filter(struct sk_buff *skb, struct sock *sk,
> unsigned res)
> +static inline int run_filter(struct sk_buff *skb, struct sock *sk,
And there.
But I fixed these up and applied the patch to net-2.6.19
I think we seriously need to think about fixing this bug,
in so me form, for 2.6.18
