OK I got that :) /proc/sched_debug is enabled by CONFIG_SCHED_DEBUG, os it's
kind of configuration issue. Before I thought that failing "grep -q -w "cpu"
/proc/cgroups" means failure/bug found by test, but it's not.

So I'm ok with this change.

IMHO that's not true (see my reply to cover letter).

Kind regards,
