I prefer that the above flag would only be introduced after a need appears to disable MCQ, e.g. discovery of a host controller that is too broken to enable MCQ.
Since UFSHCI 4.0 controllers must support UFSHCI 3.0, shouldn't users have a way to disable MCQ, e.g. via a kernel module parameter?
Thanks, Bart.
