I think we are better of with the forward declaration instead of adding more intra header dependencies, which will slow down the build and will produces artifacts in the CI runs (increases of reported warning in the incremental build, as any warns from the included header will be 'propagated' to more files). >>> +extern int macvlan_common_newlink(struct net_device *dev, >>> + struct rtnl_newlink_params *params, >>> struct netlink_ext_ack *extack); >>> >>> extern void macvlan_dellink(struct net_device *dev, struct list_head *head); >> >> >> [...] >>> diff --git a/include/net/rtnetlink.h b/include/net/rtnetlink.h >>> index bc0069a8b6ea..00c086ca0c11 100644 >>> --- a/include/net/rtnetlink.h >>> +++ b/include/net/rtnetlink.h >>> @@ -69,6 +69,42 @@ static inline int rtnl_msg_family(const struct nlmsghdr *nlh) >>> return AF_UNSPEC; >>> } >>> >>> +/** >>> + * struct rtnl_newlink_params - parameters of rtnl_link_ops::newlink() >> >> The '\t' after '*' should be single '\s'. >> >> Same for lines below. > > This is copied from other structs in the same file. Should I change it? https://elixir.bootlin.com/linux/v6.13.2/source/Documentation/process/maintainer-netdev.rst#L376 In this series, just use the good formatting for the new code. Thanks, Paolo
