I believe this statement is wrong.
fsync should force all data to disk. Period. Regardless of using ext2,
ext3, or reiserfs.
ext3/reiserfs *may* gain some benefit if running with -F, but even then,
I believe both still only journal meta-data, not the data itself, so you
could still have data stuck in cache if you don't use fsync.
