Any reason for no mailing list on CC? No, my fault. I setup get_maintainer.pl to be called from git send-email, but looks like i did it wrong :-) > Ah, and any synchronization required in case it is possible for a CPU > to leave the cpu_present_mask? Or can they only be added? Hmm... I think the main question is, whether it is ok for a cpu to be removed from the system when rcutorture is running? In both cases it would disappear from the cpu online mask, so i don't think the patch would change the behaviour. But i can check and send additional patches if there are other places that needs adjustment. Regards Sven
