  cgroup: adjust criteria for rstat subsystem cpu lock access (2025-05-30 14:36:13 -1000)

----------------------------------------------------------------
cgroup: A fix for v6.16-rc1

rstat per-subsystem split change skipped per-cpu allocation on UP configs;
however even on UP, depending on config options, the size of the percpu
struct may not be zero leading to crashes. Fix it by conditionalizing the
per-cpu area allocation and usage on the size of the per-cpu struct.
