Hi Izik, Nice. I think you want some sort of aging mechanism here. Walk through all translations of a shadow page clearing the referenced bit of all mappings it holds (and moving pages with any accessed translation to the head of the list). Because the active_mmu list position only indicates the order in which those pages have been shadowed, not how frequently or recently they have been accessed. And then have a maximum number of pages that you walk (nr_to_scan) on each shrinker callback run. Oh, I don't think you want to free more than one page on each run (right now you can free a large of chunk per run). ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
