    sys/ufs/ufs          ufs_lookup.c 
  Log:
  Allow VM object creation in ufs_lookup. (If vfs.vmiodirenable is set)
  Directory IO without a VM object will store data in 'malloced' buffers
  severely limiting caching of the data. Without this  change VM objects for
  directories are only created on an open() of the directory.
  TODO: Inline test if VM object already exists to avoid locking/function call
  overhead.
