--- Comment #20 from Alan Somers <asomers@FreeBSD.org> ---
(In reply to Konstantin Belousov from comment #19)
> But if nomsyncafterwrite is set, is there an inconsistency even without
copy_file_range?

Yes.

> For the second part, I mean that most likely this knobs works because msyncs
> are interlined with writes, and really msync affects the next write result,
> not the previous.
