Understood.

I used a netdev prefix and placed it in skbuff.h which was stupid. The
screw-up was because I was partially reverting a patch that deleted
netdev_alloc_page but I didn't need any device information so the naming
was poor. I renamed netdev_alloc_page to skb_alloc_page and will fix up
the documentation appropriately.
Thanks.
