38# DESCRIPTION:
39# Tests file truncation within ZFS while a sync operation is in progress.
40#
41# STRATEGY:
42# 1. Copy a file to ZFS filesystem
43# 2. Copy /dev/null to same file on ZFS filesystem
44# 3. Execute a sync command
45#
46# TESTABILITY: explicit
47#
48# TEST_AUTOMATION_LEVEL: automated
49#
50# CODING_STATUS: COMPLETED (2005-07-04)
