  Modified files:
    sys/dev/vinum        vinumio.c 
  Log:
  Get Vinum up and running with GEOM:
  
  (1) Use namei() and devfs to discover devices rather than a hard-coded
      MAKEDEV implementation.  Once rootfs is in place, this will allow
      Vinum to be used for the root file system partition.
  
  (2) Pass FREAD to device opens so that GEOM will return sector size
      rather than an error on attempts to read label data.
  
  (3) Avoid clobbering return values from close_drive() and masking this
      failure, resulting in a later divide by zero due to not having
      updated the Vinum-cached sector size.
  
  (4) Ignore failures from DIOCWLABEL as that appears not to be required
      in the GEOM environment.
  
  We've done testing in simple Vinum environments, but those with more
  complex environments might want to give this a spin in DP2 and make
  sure everything is up to speed.
