Preemption Model
└─>Scheduler controlled preemption model
In linux kernel since version 6.13 (release Date: 2025-01-19)
This option provides a scheduler driven preemption model that
is fundamentally similar to full preemption, but is less
eager to preempt SCHED_NORMAL tasks in an attempt to
reduce lock holder preemption and recover some of the performance
gains seen from using Voluntary preemption.
