Subject: [PATCH] udp: Unbreak modules that rely on external __skb_recv_udp() availability
Date: Thu, 4 Oct 2018 13:37:32 +0200 (CEST)	[thread overview]
Message-ID: <nycvar.YFH.7.76.1810041335180.14430@cbobk.fhfr.pm> (raw)

From: Jiri Kosina <jkosina@suse.cz>

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().
