  38 # DESCRIPTION:
  39 # xattr file sizes count towards normal disk usage
  40 #
  41 # STRATEGY:
  42 #       1. Create a file, and check pool and filesystem usage
  43 #       2. Create a 200mb xattr in that file
  44 #       3. Check pool and filesystem usage, to ensure it reflects the size
  45 #          of the xattr
  46 #
