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:
