Abstract
A method is used in managing cache pages. A location pointer is maintained in a dynamic list of entries for cache page cleaning. The dynamic list includes a list of cache pages ordered from most recently used to least recently used. Based on flags associated with the cache pages, a count of the number of cache pages processed for cache page cleaning is maintained. In response to a change in the dynamic list, the location pointer and count are updated based on the processing status of an entry to which the change pertains.
