Can I assume that the data corruption can happen on > ext3 too? It depends on the way the filesystem handles parallelism when doing direct IO. In general, though, you cannot rely on the filesystem maintaining data coherence if you mix concurrent buffered/mmap IO and direct IO to the same file. Filesystems do make efforts to minimise the possibility of coherency problems, but they cannot be prevented entirely. Hence the delegation of responsibility to the application issuing the direct IO.
