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.
