I agree that the name of the flag does not change what we intend
it to do... which is to say the storage can not be reached by
directly accessing the physical device.

If you can say that with a straight face, you must not have
had much experience with commercial application developers.
No matter how carefully your try to explain it, "NO_DIRECT" is
going to be confused with the O_DIRECT feature.
What I'm saying is that we should find some other name for
the flag than "NO_DIRECT" because it is easier than trying
to explain away the confusion. Any other suggestions?
