Thanks for your reply, Evgeniy,

Ok
> You can also add shared-info destructor, which could be used by other
Kind of:
struct skb_shared_info {
atomic_t dataref;
....
+void (*destructor)(struct sk_buff *skb, void *
destructor_arg);
+void * destructor_arg;
};
Should I call this new destructor from skb_release_data() before
kfree(skb->head) ?
or in skb_release_head_state()? close to current destructor call
Best regards,
Johann
