But no strong opinion. :) If taking care of those races is not an herculean effort, I'd go with allowing offlining + disallow re-onlining. Mainly because memory RAS stuff. Now, to the re-onlining thing, we'll have to come up with a way to check whether a section contains hwpoisoned pages, so we do not have to go and check every single page, as that will be really suboptimal. -- Oscar Salvador SUSE Labs
