Description:
The kernel's CPU scheduler currently offers several preemption modes that implement a range of tradeoffs between system throughput and response time. Back in September 2023, a discussion
on scheduling led to the concept of "lazy preemption", which could
simplify scheduling in the kernel while providing better results. Things
went quiet for a while, but lazy preemption has returned in the form of this patch series from Peter Zijlstra. While the concept appears to work well, there is
still a fair amount of work to be done.
