We should continue the conversation from last year on the topic of page fault scalability. I presume that by the time of the conference Suren's current patches for per-VMA locks [1] [2] will be at least in Andrew's tree, even if not quite upstream yet. We will then be in a good place to discuss enhancements: - File-backed VMAs - UFFD - Swap - Improve performance for low-thread-count apps - Full RCU handling of (some) page faults Suren Baghdasaryan, Liam Howlett, Michel Lespinasse, Laurent Dufour, Peter Xu would all be good participants.
