I was planning to send a patch to abstract frag->size manipulation and
ease upcoming truesize certification work.

static inline int skb_frag_size(const skb_frag_t *frag)
{
	return frag->size;
}

static inline void skb_frag_size_set(skb_frag_t *frag, int size)
{
	frag->size = size;
}

static inline void skb_frag_size_add(skb_frag_t *frag, int size)
{
	frag->size += size;
}

static inline void skb_frag_size_sub(skb_frag_t *frag, int size)
{
	frag->size -= size;
}

Is it OK if I send a single patch right now ?

I am asking because it might clash a bit with Ian work.
