Nit: someone who is reading this changelog a year from now will be quite confused - how do they work out what the race was? I'll add : See "thp: fix MADV_DONTNEED vs. numa balancing race" for more details. to the changelogs to help them a bit. Also, it wasn't a great idea to start this series with a "Restructure code in preparation for a fix". If people later start hitting this race, the fixes will be difficult to backport. I'm OK with taking that risk, but please do bear this in mind in the future.
