Hi all,

After merging the akpm tree, today's linux-next build (x86_64
allmodconfig) failed like this:

ERROR: modpost: "cgroup_get_e_css" [drivers/nvme/host/nvme-fc.ko] undefined!
ERROR: modpost: "cgroup_get_e_css" [drivers/block/loop.ko] undefined!

Caused by patch

  kernel/cgroup/cgroup.c: don't export cgroup_get_e_css twice

I am not sure what happened here, but this patch interacts with commit

  6b658c4863c1 ("scsi: cgroup: Add cgroup_get_from_id()")

from the scsi-mkp tree which adds the EXPORT_SYMBOL_GPL().

I have reverted that akpm tree patch for today.
