ABSTRACT:
Disclosed is a computer implemented method, apparatus and computer program product for communicating virtual memory page status to a virtual memory manager. An operating system may receive a request to free a virtual memory page from a first application. The operating system determines whether the virtual memory page is free due to an operating system page replacement. Responsive to a determination that the virtual memory page is free due to the operating system page replacement, the operating system inhibits marking the virtual memory page as unused. Finally, the operating system may insert the virtual memory page on an operating system free list.
