This change was motivated by a real (non-public) app that issues FSCTL_DUPLICATE_EXTENTS_TO_FILE to clone file ranges; without it, the app fails during its copy/patch phase. I can’t share the app, but I validated the code path against that workload.
Okay, thanks, that's probably good enough then. We do still need tests, and there's some other comments that haven't been addressed yet. Of course, this won't be committed until after code freeze anyway. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9732#note_125829
