How about the following?

Interface file is named "cpuset.cpus.partition" as it's a partition of
cpus. The writeable keys are "root" and "member" - a partition root
and a partition member. When "root" is requested but can't be
satisfied it shows "root invalid". This seems pretty consistent with
cgroup.type and other cpuset files.

Thanks.
