I have no idea how you decided whom to Cc:, but I recall these two threads that worked in the same "interaction between repack and promisor objects" area (I am not saying and I do not think they addressed the same problem as you are): * https://lore.kernel.org/git/20240925072021.77078-1-hanyang.tony@xxxxxxxxxxxxx/ * https://lore.kernel.org/git/cover.1730491845.git.jonathantanmy@xxxxxxxxxx/ so asking review from the authors of these topics would be more relevant than sending it to me (I did that already, and that is why the remainder of the original patch is not culled from this response---after the next line, there is nothing I wrote but the original patch left for others' convenience).
