[RFC 1/1] sched/fair: Consider asymmetric scheduler groups in load balancer

2023-05-15 Thread Tobias Huschle
The current load balancer implementation implies that scheduler groups, within the same domain, all host the same number of CPUs. This is reflected in the condition, that a scheduler group, which is load balancing and classified as having spare capacity, should pull work from the busiest group, if
