Thanks Sven!

Just wanted to note that there seem to be some false positives in
there.

"[net/batman-adv/multicast.c:1181]: (style) The function 'batadv_mcast_flags_seq_print_text' is never used."
-> used in debugfs.c


Also the header suggestions seem a bit unreliable to me,
the following removals are false positives, I think:

* header removals in compat-sources/*
  -> breaks compiling

* linux/icmp6.h in multicast.c
  -> icmp6_hdr()
* linux/ipv6.h in multicast.c
  -> ipv6_hdr()

* net/addrconf.h in multicast.c
  -> ipv6_mc_check_mld()
  -> ipv6_addr_is_ll_all_nodes()
* net/ip.h in multicast.c
  -> ip_eth_mc_map()
* net/ipv6.h in multicast.c
  -> IPV6_ADDR_MC_SCOPE
  -> IPV6_ADDR_SCOPE_LINKLOCAL

Moving the following includes upwards seems unnecessary:
* linux/if_bridge.h in multicast.c
* linux/igmp.h in multicast.c

The following removals seem correct \o/:
* linux/in6.h in multicast.c
* net/mld.h in multicast.c

Additionally, the following include seems to be missing but wasn't
caught by the scripts:
* net/if_inet6.h in multicast.c
  -> ipv6_eth_mc_map()


Let me know whether this seems about right. Or whether I am
missing #includes in my->head :).

Regards, Linus


PS: I also do not understand the sparse complaints regarding
ip_eth_mc_map(). The according include is currently there, seems
to compile fine.
