Hence, I have worked on this new approach which is more generic and hopefully should work in most cases. This approach fundamentally changes the way union stacks are maintained. Details of the approach can be found in the accompanying documentation patch. Since this is still a work in progress, there are many loose ends. Apart from that, I have some questions about the design and implementation aspects, which I have raised in the documenation patch. It will be very helpful if people who are familiar with VFS and stackable filesystems could review this. This series (on 2622rc4mm2) has the following 4 patches: 1/4 - Union mount documentation. 2/4 - Mount changes to support union mount. 3/4 - Lookup changes to support union mount. 4/4 - Directory listing support for union mounted directories. Kindly review and send me your feedback.
