    sys/vfs/specfs       spec_vnops.c 
  Log:
  Deal with revoke()'d descriptors.  The underlying vnode is vgone()'d, which
  means that it is forceably closed.  This clears v_rdev even though file
  descriptors may still have references to the vnode, which leads to panics
  (mainly on tty devices).
  
  Check for v_rdev == NULL in most specfs fileops calls and return an error
  code instead of panicing.   This isn't the cleanest solution but it's fine
  for now.
