Is there any evidence that anyone anywhere has ever lost data because
of a lack of directory fsyncs? I sure don't recall any bug reports
that seem to match that theory.
It seems to me that we're talking about a huge hit in both code
complexity and performance to deal with a problem that doesn't actually
occur in the field; and which furthermore is trivially solved on any
modern filesystem by choosing the right filesystem options. Why don't
we just document those options, instead?
