I've been struggling with similar issue in centos 6.6. In previous version (6.5) everything worked fine, but after update I wasn't able to set socket for ssh control master on overlayfs. I made some tedious research and comparisons and it turned out that it's not about the kernel (made few downgrades) but ssh.
According to https://bugzilla.redhat.com/show_bug.cgi?id=953088 in ssh version included in RHEL 6.6 (and CentOS) there was a patch witch modifies behaviour of creating control socket. When I downgraded ssh packages (openssh{,-clients,-server}) to the version without that patch (5.3p1-94.el6) everything worked like a charm!
I hope it will also help you to solve your problem in Ubuntu.
