Subject: [PATCH next-20130703] net: sock: Add ifdef CONFIG_MEMCG_KMEM for mem_cgroup_sockets_{init,destroy}
Date: Wed, 3 Jul 2013 14:14:53 +0200 [thread overview]
Message-ID: <1372853693-15303-1-git-send-email-sedat.dilek@gmail.com> (raw)
When "CONFIG_MEMCG_KMEM=n" I see this in my build-log:
...
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.
