[PATCH net-next 1/5] net, atm/ambassader: convert skb->tail into skb_tail_pointer(skb)

[PATCH net-next 1/5] net, atm/ambassader: convert skb->tail into skb_tail_pointer(skb)

[Isaku Yamahata]

The change set of 27a884dc, "[SK_BUFF]: Convert skb->tail to sk_buff_data_t"
converted skb->tail from pointer into sk_buff_data_t. It missed skb->tail
in drivers/atm/ambassador.c.
This patch converts skb->tail into skb_tail_pointer(skb).

Found by inspection. Compile tested only.

[PATCH net-next 2/5] net, scsi/csgb4i: convert skb->transport_header into skb_transport_header(skb)

[Isaku Yamahata]

The change set of 1a37e412, "net: Use 16bits for *_headers fields
of struct skbuff" converted from sk_buff_data_t into 16bit integer.
So skb->tail needs to be converted to skb_tail_pointer(skb).

[PATCH net-next 3/5] mv643xx_eth.c: convert skb->end into skb_end_poitner(skb)

[Isaku Yamahata]

The change set of 4305b541 "[SK_BUFF]: Convert skb->end to sk_buff_data_t"
converted skb->end from pointer to sk_buff_data_t.
The pointed value should be accessed via skb_end_pointer().

Since arm or ppc arch doesn't define NET_SKBUFF_DATA_USES_OFFSET,
skb->end is effectively pointer. So it doesn't cause a real problem.
But this patch is good for consistency.

Found by inspection. Compile test only.

[PATCH net-next 5/5] staging/rtl8192u: convert skb->tail into skb_tail_pointer(skb)

[Isaku Yamahata]

The change set of 7a884dc "[SK_BUFF]: Convert skb->tail to sk_buff_data_t"
converted skb->tail from pointer into sk_buff_data_t.
Thus skb->tail is not always pointer, the area pointed by skb->tail
should be accessed via skb_tail_pointer().
