  19 # Description:
  20 # Verify that holes can be written and read back correctly in ZFS.
  21 #
  22 # Strategy:
  23 # 1. Create a testfile with varying holes and data throughout the file.
  24 # 2. Verify that each created file has the correct number of holes and
  25 # data blocks as seen by both lseek and libzfs.
  26 # 3. Do the same verification for a largefile.
  27 # 4. Repeat for each recsize.
