The the "Lazy preemption" model (CONFIG_PREEMPT_LAZY=y) was merged for #Linux 6.13.
It optimizes fair-class preemption by delaying preemption requests to the tick boundary, while working as full preemption for RR/FIFO/DEADLINE classes.
In the end it hopefully will thus allow distributions to ship one äkernel that can serve both regular needs as well as RT needs.
