Identifying replacement memory pages from three page record lists

摘要

A replacement memory page is identified by accessing a first list of page records, and if the first list is not empty, identifying a replacement page from a next page record indicator of the first list. A second list of page records is accessed if the first list is empty, and if the second list is not empty, the replacement page is identified from a next page record indicator of the second list. A third list of page records is accessed if the first and second lists are empty, and the replacement page is identified from a next page record indicator of the third list.
