21# Description:
22# Verify redacted send can deal with a large redaction list.
23#
24# Strategy:
25# 1. Create 64 clones of sendfs each of which modifies two blocks in a file.
26#    The first modification is at an offset unique to each clone, and the
27#    second (the last block in the file) is common to them all.
28# 2. Verify a redacted stream with a reasonable redaction list length can
29#    be correctly processed.
