Hi... > what is exact difference between page replacement and page reclaiming? > sry for such silly question...... Here is my understanding: - reclaim refers to the work of VM manager putting inactive pages into soon-to-be freed pages - replacement refers to the work of determining which pages should be evicted to the backing storage or swapped. maybe this includes which page should be brought back to RAM from swap. regards, Mulyadi. -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
