> Socket memory can be a significant share of overall memory consumed by
> common workloads. In order to provide reasonable resource isolation in
> the unified hierarchy, this type of memory needs to be included in the
> tracking/accounting of a cgroup under active memory resource control.
> 
> Overhead is only incurred when a non-root control group is created AND
> the memory controller is instructed to track and account the memory
> footprint of that group. cgroup.memory=nosocket can be specified on
> the boot commandline to override any runtime configuration and
> forcibly exclude socket memory from active memory resource control.
