You write that this isn't the right way to collect per cgroup stats. What is

Well, there's nothing specific to mq-deadline or any other elevator or
controller about the stats that your patch collected and showed. That
seems like a pretty straight forward sign that it likely doens't
belong there.
Do you perhaps want these statistics to be reported via read-only cgroup
attributes of a new cgroup policy that is independent of any particular
I/O scheduler?
Thanks,
Bart.
