No... This patch is still not correct..

It's mem_cgroup_create() but not enable_swap_cgroup() that needs
to be marked as __init_refok.

Here is the correct one:

Subject: [PATCH] memcg: fix section mismatch

At system boot when creating the top cgroup, mem_cgroup_create() calls
enable_swap_cgroup() which is marked as __init, so mark mem_cgroup_create()
as __init_refok to avoid false section mismatch warning.
