function name scaling (1) arch_scale_cpu_capacity() - uarch (2) get_actual_cpu_capacity() - hw + cpufreq/thermal of (1) (3) capacity_of() - rt (rt/dl/irq) of (2) (used by fair) Although (1) - (3) are very close to each other from the functional standpoint, their names are not very coherent. I assume this makes it hard to understand all of this when reading the code w/o knowing these patches before. Why is (2) tagged with 'actual'? This is especially visible in feec() where local variable cpu_cap relates to (3) whereas cpu_actual_cap related to (2). [...]
