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. - Arnaldo - To unsubscribe from this list: send the line "unsubscribe dccp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
