I did a quick test and for new connection the cgroup2 match worked as
expected. For an existing connection I wasn't able to trigger the match.

It is quite likely I do something wrong:

	ssh into the box
	# mkdir /sys/fs/cgroup/test
	# echo $$ > /sys/fs/cgroup/test/cgroup.procs
	# echo $PPID > /sys/fs/cgroup/test/cgroup.procs
	# iptables -A OUTPUT -m cgroup --path test

Should I see matches with the existing ssh session?

cheers,
daniel
