The Linux buffer cache has NO ordering constraints at all, and hence
it is obviously faster at doing directory operations.  What does this
mean?  It means that if you crash that machine at the right time, your
filesystem will be utterly fucked.

If any Linux bigot listening in on this mailing list now decides to
start ranting that this is true, please go elsewhere.  This is not the
right forum for you to contradict the massive amounts of filesystem
research literature.
