IMO it doesn’t make much sense to call things that run on the CPU “direct.” Direct access to resources is the assumption if you are running on the CPU, right?
Point taken. In retrospect, directfs is not a good name as it gives the impression of a new filesystem implemention. I should have named this more along the lines of "direct access mode" as some of you have pointed out.
I think the comment which was in response to mine is pretty ambiguous, it isn’t obvious to me what they mean by “here” (in the article, in the comment I responded to, or in my comment?).
