I'm a little confused about this new type of preemption.

"The long road to lazy preemption" [1] article says:

"The lazy mode will occupy a place between PREEMPT_NONE and PREEMPT_VOLUNTARY, 
replacing both of them."

Whereas Linux 6.13 change log [2] says:

"lazy preemption" mode that aims to be a bridge between the voluntary and the 
full preemption mode"

I think Fedora would be interested in the latter, by default, for all Fedora 
Linux variants.

For some time, Fedora Workstation working group has been interested in 
implementing full preemption, but there's been  concern about enabling it 
across the board among all Fedora variants. [3]

So the first question is if lazy is somewhere between voluntary and full, and 
if it is, how would we go about testing it in advance of making it the default?
