Linux supports fsync() on directories to flush metadata to disk. Is there
any work to to implement fsync() on directories under Linux? Are there
any patches anywhere for this? If not, what filesystem operations does
Cyrus assume will update directory entries synchronously? Anything other
than open() and rename()? link()/unlink()? Anything else?
