IIRC, Al vetoed the NFS cto change that went into 2.4.x because he claimed he was planning on providing an alternative fix that would better fit the unionfs. As that apparently won't materialize in 2.6.x, I'm in any case planning on presenting the open(".") patch (or some variant of it) to Linus. That said, just backing a bugfix out of a stable kernel without providing an alternative solution should only be done in those cases where keeping it would cause a worse problem. For instance if the fix is a security issue...
