It isn't a fix, and we don't plan to support the feature it subsequently enables in anything older than 5.13. Unless there is a another pressing reason for adding this patch, I suggest it is dropped from 5.10, 5.11 and 5.12 stable branches. Thanks, M. -- Without deviation from the norm, progress is not possible.
