Ah, right, the percentage is out of the total device resources
regardless of the hierarchical restrictions. I still don't think it's
a good idea for rdmacg to deviate from the common interface
conventions. If you want to do the percentage calculation in the
userland and the base numbers are system-wide numbers which are
hardware dependent, it'd be best if there's an existing place where
the numbers can be exposed naturally. That'd be more in line with
others too. The amount of total resources available for the device
isn't tied to cgroup after all.
Thanks.
