Apologies in advance!!! I have rebased printk/linux.git, branch rework/console-list-lock on top of srcunmisafe.2022.12.01a, commit 51f5f78a4f804aeb73cf ("srcu: Make Tiny synchronize_srcu() check for readers"). I hope that it will be OK. Thanks a lot for nailing this down. It looked like a mystery to me. Best Regards, Petr
