35#
36# DESCRIPTION:
37#
38# Verify the integrity of non-aligned writes to the same blocks within the same
39# transaction group, where an fsync is issued by a non-final writer.
40#
41# STRATEGY:
42
43# This test verifies that the unoverride in the following sequence of events is
44# handled correctly:
45#
46# 1) A new transaction group opens
47# 2) A write is issued to a certain block
48# 3) The writer fsyncs() that file
49# 4) TBD module immediately writes that block, then places an override in the
50#    syncer's TBD data structure, indicating that it doesn't need to write that
51#    block when syncing.
52# 5) Another write is issued to the same block, with different data.
53# 6) TBD module unoverrides that block in the syncer's TBD data structure
54# 7) The syncer writes that block
55#
56#
57# TESTABILITY: explicit
58#
59# TEST_AUTOMATION_LEVEL: automated
60#
61# CODING_STATUS: BEGIN (2013-1-21)
