[$] The long road to lazy preemption

Date:

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.
