I'm sorry but I'm not sure I figured what you mean by "the scheduler private per-pcpu area"... Do you perhaps mean making it a member of `struct csched_pcpu' ?Yes, that's what I would suggest.Ok then, functionally, that is going to be exactly the same thing as where it is right now, i.e., a set of global per_cpu() variables. It is possible for your solution to bring some cache/locality benefits, although that will very much depends on single cases, architecture, workload, etc. The space is only allocated if sched_credit is responsible for the pcpu.
