Ouch. Pavel, it's just completely wrong. First of all, no_file() is
bogus wrt symlinks. Moreover, it imposes a lot of overhead on _every_
mkdir()/creat()/mknod()/symlink()/link(). BTW, in the 'nonclean' variant
it messes with CVS, pine, whatnot.
What are you using it for? I _seriously_ suspect that there are better
ways to achieve the effect you actually need. Care to describe?
