Slightly off the title. As we are moving to use cgroup to limit PASID
allocations, it would be much simpler if we enforce on the current
task.  

Yes I think we should do that. Is there a problem with charging the
process that does the PASID allocation even if the PASID indexes some
other mm?

Besides complexity, my second concern is that we are sharing the misc
cgroup controller with other resources that do not have such behavior.

Cgroup v2 also has unified hierarchy which also requires coherent behavior
among controllers.

Thanks,

Jacob
