Ok. Sounds good. In fact, it's something I've wanted for a while, since it's also potentially the solution to performance-critical things like virtual filesystems based on revision control logic etc (traditionally done with fake NFS servers). I did a very very quick scan, and didn't see anything that raised my hackles. But it's late in the 2.6.x game, and as a result I'm not going to apply it until I get a lot of feedback from actual users too. Linus
