Good question, if it doesn't matter, you might as well log garbage.

There are a lot of logical holes in this discussion.

Real UIDs are always reported at sendmsg() time, not effective ones
(the UID "at sendmsg() time").

Therefore if we were to add CGROUP passing at sendmsg() time it should
report the "real cgroup", the one the task has at the time the file
descriptor / socket was "created".
