ACK, except that  I wouldn't use _GPL in the export - it's trivial to
reproduce, so we are not protecting anything here.  And all that code
has been moved verbatim from seq_path(), which is mine *and* exported
without _GPL nonsense.

As far as I'm concerned, all these helpers are as general-purpose as atoi()
et.al. - library functions damn close to being non-copyrightable due both
to triviality and to being absolutely straightforward implementations -
tell anybody to implement it and that's what you'll get.

I'm not fond of proprietary modules, to put it mildly, but let's not get
completely ridiculous.  In this case it's as dumb as schools trying to ban
aspirin in the name of War On Some Drugs.
