The patches all look fine to me, but it's clearly too late now. What is the actual dependency for KASAN, do you just need a longer command line or something else? If it's just the command line size, I would suggest that Palmer can still pick up a oneline change to increase it and refer to this thread in the changelog as a reference for why it is not an actual UAPI break.
