Why is > this important? The resource controller assumes that pages in pzones are linked to LRU lists or free lists in order to simplify the cleanup of pzones in classes. Cleaning up a pzone needs to know all the pages that belong to the pzone. So the resource controller is designed not to allocate pages from pzones that will never end up in the LRU. -- KUROSAWA, Takahiro ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
