Btw, once again, the vfs layer function you took this from *does* have
some reason to worry. Somebody might be doing 'pipe()' in a loop.

Also, if your worry is "what if somebody mounts that thing a million
times", the solution to *that* would have been to make it a per-sb
counter, which I think would be cleaner anyway.

But my real issue is that I think you would be *much* better off just
deleting code, instead of adding new code.

For example, what purpose does 'e->dentry' and 'ei->d_childen[]' have?
Isn't that entirely a left-over from the bad old days?

So please try to look at things to *fix* and simplify, not at things
to mess around with and make more complicated.
