[$] Utilization inversion and proxy execution

Over the years, the kernel's CPU scheduler has become increasingly aware ofhow much load every task is putting on the system; this information is usedto make smarter task placement decisions. Sometimes, though, this logiccan go wrong, leading to a situation that Valentin Schneider describes as"utilization inversion". At the 2020 Power Management and Schedulingin the Linux Kernel summit (OSPM), he described the problem and someapproaches that are being considered to address it.
