I assume you refer to
Message-Id: <20240331174442.51019-1-haitao.huang@linux.intel.com>
right?
Could it be even simpler if you didn't stick to cgtools APIs and v1
compatibility?
Reducing ash_cgexec.sh to something like
echo 0 >$R/$1/cgroup.procs
shift
exec "$@"
(with some small builerplate for $R and previous mkdirs)
Thanks,
Michal
