Sorry for late.
I checked source code of sysbench and found that the actual default
value of --file-fsync-freq is 100 instead of 0 in man page, as in the
following lines.
{"file-fsync-freq", "do fsync() after this number of requests (0 - don't use
fsync())",
SB_ARG_TYPE_INT, "100"},
I double checked that via a debug patch to sysbench too.
