Ok. It pins using an elevated refcount. Same as XPmem right now. With that we effectively pin a page (page migration will fail) but we will continually be reclaiming the page and may repeatedly try to move it. We have issues with XPmem causing too many pages to be pinned and thus the OOM getting into weird behavior modes (OOM or stop lru scanning due to all_reclaimable set). An elevated refcount will also not be noticed by any of the schemes under consideration to improve LRU scanning performance. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
