> It all adds up to a lot to be done still, but the end result of the lazy-preemption work should be a kernel that is a bit smaller and simpler while delivering predictable latencies without the need to sprinkle scheduler-related calls throughout the code. That seems like a better solution, but getting there is going to take some time.
Sounds promising. Just like EEVDF, this both simplifies and improves the status quo. Does not get better than that.
