If anyone has any objections, please let me know. ------------------ From: Jiri Kosina [ Upstream commit 7e823644b60555f70f241274b8d0120dd919269a ] Commit 2276f58ac589 ("udp: use a separate rx queue for packet reception") turned static inline __skb_recv_udp() from being a trivial helper around __skb_recv_datagram() into a UDP specific implementaion, making it EXPORT_SYMBOL_GPL() at the same time. There are external modules that got broken by __skb_recv_udp() not being visible to them. Let's unbreak them by making __skb_recv_udp EXPORT_SYMBOL(). Rationale (one of those) why this is actually "technically correct" thing to do: __skb_recv_udp() used to be an inline wrapper around __skb_recv_datagram(), which itself (still, and correctly so, I believe) is EXPORT_SYMBOL().
