I just went and attempted to reproduce this, and on RHEL6 workstation
(aka my work laptop), using the todays 4.2.0-rc6+ aka
edf15b4d4b01b565cb5f4fd2e2d08940b9f92e2f and all of the mounts in
/proc/self/mounts are the same between 4.2.0-rc6 and the RHEL6 stock
2.6.32-504.30.3.el6.x86_64, including the cgroups mounted on /cgroup.

I built a few more kernels just to see if this was some weird backport
thing. The kernels 3.10.86, 3.14.58, 3.18.20, and 4.1.5 all boot and
mount their cgroup filesystems just fine.  Granted I kept having to
smack the memory cgroup into being compiled in as the config options
kept changing but otherwise I have not seen any problems.

So I am very surprised you are having problems.

Although I guess I could have saved myself some time by noticing that
4.1.5 was the only one of the kernels with the change backported into
it.  *Shrug*

I don't see the problem and I don't know where to look to see why you
are having problems.
