A few weeks ago, I posted the design of aufs. And here are source files. I have another version which dropped many features and the size became about half because such suggestion was posted LKML. But I got no response for it. Additionally I am afraid it is useless in real world since the dropped features are so essential. This version here I am posting is full aufs2 against the mainline (linux-2.6.git). Kindly review and let me know your comments. And please consider incorporating into mainline. J. R.
