  34 # DESCRIPTION:
  35 # The noxattr mount option functions as expected
  36 #
  37 # STRATEGY:
  38 #       1. Create a file on a filesystem and add an xattr to it
  39 #       2. Unmount the filesystem, and mount it -o noxattr
  40 #       3. Verify that the xattr cannot be read and new files
  41 #          cannot have xattrs set on them.
  42 #       4. Unmount and mount the filesystem normally
  43 #       5. Verify that xattrs can be set and accessed again
  44 #
