  35 # DESCRIPTION:
  36 # Write a file to the allowable ZFS fs size.
  37 #
  38 # STRATEGY:
  39 # 1. largest_file will write to a file and increase its size
  40 # to the maximum allowable.
  41 # 2. The last byte of the file should be accessbile without error.
  42 # 3. Writing beyond the maximum file size generates an 'errno' of
  43 # EFBIG.
