Note that the above is a v5.18 based shortlog and diffstat, but because the
RCU tree deep-merged one of the scheduler commits that introduced better,
Kconfig-invariant preemption model accessors:
cfe43f478b79 preempt/dynamic: Introduce preemption model accessors
... and you merged the RCU tree already, so you'll get this shortlog &
diffstat:
=============>
