Merge tag 'cgroup-for-6.16-rc1-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup

Pull cgroup fix from Tejun Heo:
 "The 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"
