  Hi all,

After merging the net-next tree, today's linux-next build (sparc64
defconfig) failed like this:

drivers/net/ethernet/sun/sunvnet_common.c: In function 'vnet_handle_offloads':
drivers/net/ethernet/sun/sunvnet_common.c:1277:16: error: implicit declaration of function 'skb_gso_segment'; did you mean 'skb_gso_reset'? [-Werror=implicit-function-declaration]
 1277 |         segs = skb_gso_segment(skb, dev->features & ~NETIF_F_TSO);
      |                ^~~~~~~~~~~~~~~
      |                skb_gso_reset
drivers/net/ethernet/sun/sunvnet_common.c:1277:14: warning: assignment to 'struct sk_buff *' from 'int' makes pointer from integer without a cast [-Wint-conversion]
 1277 |         segs = skb_gso_segment(skb, dev->features & ~NETIF_F_TSO);
      |              ^

Subject: [PATCH] Fix a sparc64 use of the gso functions

This was missed when they were moved.

Thanks Stephen,

I agree that this is a correct fix.

I've tried to conduct an audit of the symbols changed in the above
mentioned patch and confirm that compilation is successful.
Your patch addresses the only failure I uncovered during that activity.

Sorry for not doing this before the patch hit net-next.

I am still applying that patch to the net-next tree merge.

Hi Stephen,

I guess it was applied after you pulled net-next.
In any case, for the record, I see it there now as:

  d9ffa069e006 ("sunvnet: fix sparc64 build error after gso code split")
