--- Comment #2 from Zdenek Sojka <zsojka at seznam dot cz> 2011-03-15 16:32:37 UTC --- Oh, sorry. It was reduced from gcc.c-torture/compile/pr44043.c: ... static inline __attribute__((always_inline)) int dst_output(struct sk_buff *skb) { return skb_dst(skb)->output(skb); }; ... NF_HOOK(2, NF_INET_LOCAL_OUT, skb, ((void *)0), rt->u.dst.dev, dst_output); ... dst_output is always_inline there, but is used in this way.
