  Modified files:
    sys/fs/nullfs        null_vfsops.c 
  Log:
  Reflect mpsafety of the underlying filesystem in the nullfs image.
  
  I benchmarked this by simultaneously extracting 4 large tarballs (basically
  world images) on a 4-processor AMD64 system, in a malloc-backed md.
  
  With this patch, system time was reduced by 43%, and wall clock time by 33%.
