These declarations were static, and had to be made public only because of DIRECT call stuff, which is an implementation detail. Polluting include/net/ipv6.h seems not appropriate. > #endif /* _NET_IPV6_H */ > diff --git a/net/core/dev.c b/net/core/dev.c > index c360bb5367e2..9a3d8768524b 100644 > --- a/net/core/dev.c > +++ b/net/core/dev.c > @@ -101,6 +101,7 @@ > #include <net/dsa.h> > #include <net/dst.h> > #include <net/dst_metadata.h> > +#include <net/ipv6.h> > #include <net/pkt_sched.h> > #include <net/pkt_cls.h> > #include <net/checksum.h> > @@ -5743,7 +5744,6 @@ static void gro_normal_one(struct napi_struct *napi, struct sk_buff *skb) > } > > INDIRECT_CALLABLE_DECLARE(int inet_gro_complete(struct sk_buff *, int)); This is odd. You move ipv6_gro_complete() but not inet_gro_complete() I think we should be consistent. > -INDIRECT_CALLABLE_DECLARE(int ipv6_gro_complete(struct sk_buff *, int)); > static int napi_gro_complete(struct napi_struct *napi, struct sk_buff *skb) > { > struct packet_offload *ptype; > @@ -5914,8 +5914,6 @@ static void gro_flush_oldest(struct napi_struct *napi, struct list_head *head) > > INDIRECT_CALLABLE_DECLARE(struct sk_buff *inet_gro_receive(struct list_head *, > struct sk_buff *)); > -INDIRECT_CALLABLE_DECLARE(struct sk_buff *ipv6_gro_receive(struct list_head *, > - struct sk_buff *)); > static enum gro_result dev_gro_receive(struct napi_struct *napi, struct sk_buff *skb) > { > u32 hash = skb_get_hash_raw(skb) & (GRO_HASH_BUCKETS - 1); > -- > 2.29.2 >
