Thanks!

Thanks! I took them both into my tree.

Thanks! > I took them both into my tree. Didn't you see my reply? I did, but I didn't see the change yet in .39-rc5, so I figured it would be harmless to also take it into the tile tree. And, I thought you might have just taken the platform-independent part of the change. I'll revert the tile part of the change out of my tree. Thanks!

This change will show up in net-next-2.6 and as a consequence linux-2.6-next -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Although these are equivalent, but the skb_checksum_start_offset() is more readable. Signed-off-by: Shan Wei <shanwei@cn.fujitsu.com> --- drivers/net/tile/tilepro.c | 2 +- net/ipv6/udp.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-)
