Ok, I saw 0day bot also started to report those which is good. For example,

lkml.org/lkml/2020/5/12/1358

which so far is nit blocking 0day on linux-next since it does not use panic_on_warn yet (while syzbot does).

Thus, I am more convinced that we should not revert the commit just for syzbot until someone could also convince 0day to select RCU_EXPERT and then DEBUG_RCU_LIST?
