35# DESCRIPTION:
36# Holes in ZFS files work correctly.
37#
38# STRATEGY:
39# 1. Open file
40# 2. Write random blocks in random places
41# 3. Read each block back to check for correctness.
42# 4. Repeat steps 2 and 3 lots of times
43#
44# TESTABILITY: explicit
45#
46# TEST_AUTOMATION_LEVEL: automated
47#
48# CODING_STATUS: COMPLETED (2005-07-04)
