There wasn't a long discussion about removing kmemcheck, it just followed up a KASan topic and the question of whether kmemcheck can be deprecated now that KASan is merged came up. No one at the room didn't use it, knew a user of it, or couldn't describe a usecase where kmemcheck was superior to KASan - so the conclusion was to try and replace it. The only thing I can really put in the changelog is a reference to the KASan docs and to ask folks to complain loudly if we missed a usecase.
