Subjectcgroup, balance RT bandwidth
From
Just to confirm, cpuset.sched_load_balance doesn't work with RT, right?
You cannot have tasks for sub-domain 2 to utilize bandwidth of
sub-domain 3, right?

2 3
(50% rt) (50% rt )

For my application domain it would be interesting to have
rt_runtime_ns as a min. of allocated rt and not a max.
Ex. If an application of domain 2 needs to go up to 100% and domain 3
is idle, then it would be cool to let it utilize the full bandwidth.
(we also could have a hard upper limit in each sub-domain, like
hard_up=0.8, i.e. even if we could get 100%, we will only utilize
80%); in other words, rt having the same cpu bandwidth management behavior
as the "best-effort" tasks.

Could this be done?
