Grr, as Greg didn't Cc the actual patches to Linus here's the objection

 - it mounts a filesystem into the init (aka global) namespace on mount
   for no good reason
 - it then manipulates it using the high-level VFS functions which it
   could just do on any filesystem if it really wanted

These lots of dicussions were basically people telling Greg that he
should come up wit ha real problem instead of just pushing it for it's
own sake.  Arjan And Eric have very well refuted the spped claim.

NACK from me from the VFS point of view - this is devfs 2.0, just worse
than the last version of devfs 1.  I would really really like to head
what the udev folks actually want instead of pushing in this crap.
