In file included from net/ipv4/tcp_ipv4.c:77 (and many more):
include/net/tcp_memcontrol.h:5: warning: ‘struct cgroup_subsys’ declared inside parameter list
include/net/tcp_memcontrol.h:5: warning: its scope is only this definition or declaration, which is probably not what you want

Add forward declarations for all used structures to fix this.
