Gitlab pain

I'm getting lost in a maze of twisty little passages, all alike. I'm looking at https://gitlab.haskell.org/ghc/ghc/merge_requests/10#note_1877 and https://gitlab.haskell.org/ghc/ghc/merge_requests/10 But the note in the former starting "Another module should reference the symbol..." doesn't show up in the latter, anywhere. How can I see the current state of play on this MR, the ground truth? Simon
