Hi Kamezawa, I've been wondering why do we have a hardcoded 120s timeout for offline_pages. This goes all the way down to when the offlining has been implemented. I am asking because I have seen many cases where memory offline fails just because of the timeout on a large machines under heavy memory load during offline operation. So I am really wondering whether we should make the timeout configurable or just remove it altogether. I would be more inclined for the later but there might have been an explicit reason for the timeout which is not clear to me. Could you clarify? -- Michal Hocko SUSE Labs
