Thanks for the review! I understand that tip/locking would be the most appropriate place but I am wondering whether this causes some issues with the follow up patches which use this new API and which I expect to go via Andrew's tree.
That being said I do not care much but then we have a potential dependency between mmotm and tip/locking.
