I am not sure about that one - I don't know all the functions calling
sk_receive_skb (cscope says ppoe.c / dn_nsp_in.c use this too).
In the TCP/DCCP case it is clear (due to the cloning while one is held under
a lock), but for other contexts it might be different and cause subtle problems.
Yup, that is why I asked, I'll investigate this further later to see
if its safe for the !INET cases.
