It looks like the same bug which was fixed by 74d0833c659a ("cgroup:
fix css_task_iter crash on CSS_TASK_ITER_PROC").  The bug got
introduced durinv v4.14 cycle and triggers when cgroup1 and cgroup2
are used at the same time, which the recent versions of systemd does
when in cgroup1 mode.

Thanks Tejun,

I'll have to upgrade my systems to the lastest stable, before doing any
other upgrades.
