Any idea when, or under what thread title, it took place? Or if it wasn't on the LKML per se but on one of the subsystem lists, got a link?
The original kernel discussion was in 2012; I read about it on LWN. Here are some relevant LWN.net links about the kernel change:
https://lwn.net/Articles/484251/ "Fixing control groups" https://lwn.net/Articles/486401/ "A proposed plan for control groups" And here's a piece about the systemd changes to accommodate it:https://lwn.net/Articles/555920/ "Changes coming for systemd and control groups"
Here's a pertinent GMANE link from the cgroups subsystem list:http://thread.gmane.org/gmane.linux.kernel.cgroups/857 "[RFD] cgroup: about multiple hierarchies"
