This project attempts to build an infrastructure for transparently maintaining coherence among page cache objects in different layers of a Linux-based stackable file system. Our Linux 2.4 prototype requires no changes to existing file systems, and involves minimal changes to the page cache code, in the form of hooks to a cache manager using a well-defined API. We are enhancing the API, applying it to other OS caches (e.g., inode, directory entry, etc.), considering new architectures and OSs, and evaluating the system. We are also exploring issues in solving more complex coherency problems related to fan-out file systems, size-changing stackable file systems and distributed file systems.
