LD init/built-in.o mm/built-in.o: In function `mem_cgroup_css_free': memcontrol.c:(.text+0x5caa6): undefined reference to `mem_cgroup_sockets_destroy' make[2]: *** [vmlinux] Error 1 Inspired by the ifdef for mem_cgroup_sockets_{init,destroy} here... [ net/core/sock.c ] ... int mem_cgroup_sockets_init() ... void mem_cgroup_sockets_destroy() ... ...I did the the same for both in "include/net/sock.h". This fixes the issue for me in next-20130703.
