  21. # Description:
    22. 

  22. # Verify redacted send can deal with a large redaction list.
    23. 

  23. #
    24. 

  24. # Strategy:
    25. 

  25. # 1. Create 64 clones of sendfs each of which modifies two blocks in a file.
    26. 

  26. #    The first modification is at an offset unique to each clone, and the
    27. 

  27. #    second (the last block in the file) is common to them all.
    28. 

  28. # 2. Verify a redacted stream with a reasonable redaction list length can
    29. 

  29. #    be correctly processed.
    30. 

  30. # 3. Verify that if the list is too long, the send fails gracefully.
