There are still some major bugs which I want to fix before posting the patches. Some key features: - VFS based approach, all file systems *should* work when mounted read-only - unification of directory listings with readdir() - copy-up with the help of J?rn's madcow patches to sendfile - whiteout implementation for the VFS and ext2 The patches basically implement a union stack with/on dentries. That is working quite well but I still have some issues with the dcache. At the moment other stuff has higher priorities.
