# ID: fsync_integrity_001_pos
#
# DESCRIPTION:
#
# Verify the integrity of non-aligned writes to the same blocks within the same
# transaction group, where an fsync is issued by a non-final writer.
#
# STRATEGY:

# This test verifies that the unoverride in the following sequence of events is
# handled correctly:
#
# 1) A new transaction group opens
# 2) A write is issued to a certain block
# 3) The writer fsyncs() that file
# 4) TBD module immediately writes that block, then places an override in the
#    syncer's TBD data structure, indicating that it doesn't need to write that
#    block when syncing.
# 5) Another write is issued to the same block, with different data.
# 6) TBD module unoverrides that block in the syncer's TBD data structure
# 7) The syncer writes that block 
#
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: BEGIN (2013-1-21)
