It is a bug fix for a feature new to > 4.17, so I suspect yes, but it is ultimately up to Henry Wang. I am planning to start the process of tagging the 4.17 so we can catch the release date next Monday before the holiday season in Europe. That said, if the EFI maintainer (Jan) is happy about including this in 4.17, I don't object it if this patch can land in the stable-4.17 branch before the end of Thursday (Dec. 8). Note that OSSTest probably needs ~1 day to do the sync from the staging-4.17 branch. Kind regards, Henry
