40# DESCRIPTION:
41# Holes in ZFS files work correctly.
42#
43# STRATEGY:
44# 1. Open file
45# 2. Write random blocks in random places
46# 3. Read each block back to check for correctness.
47# 4. Repeat steps 2 and 3 lots of times
48#
49# TESTABILITY: explicit
50#
51# TEST_AUTOMATION_LEVEL: automated
52#
53# CODING_STATUS: COMPLETED (2005-07-04)
