As you say, there's still a race. It's better to leave a gaping hole which obviously needs fixing than a subtle one, so Linus wouldn't accept it.
How about:
lock_vfs() stat() open() unlock_vfs()
As I said, it's only useful in the core dump case, but that's the original context of this discussion. We can worry about safe temp file creation later.
