I think Sasha wanted to drop this patch [1]. But as I said earlier [2], 
this patch is not wrong, it is just not needed in v5.9 because the 
"Fixes" commit 010b430d5df5 ("mptcp: MPTCP_IPV6 should depend on IPV6 
instead of selecting it") is not in v5.9.

I guess it is certainly easier to keep it because it is not wrong and 
doesn't hurt.
