The reason we might care in this case is nlm_cmp_addr() is executed

Actually, I'm not sure this assertion is correct. The only users of
nlm_cmp_addr() are nlmclnt_grant(), nlm_lookup_host() and
nlmsvc_unlock_all_by_ip().
AFAICS, the only one that needs to be v4 mapped should be
nlmclnt_grant,
which is not in a performance critical path...
So then your proposal is to ensure the two arguments of the
nlm_cmp_addr() callsite in nlmclnt_grant() are both AF_INET6?
That doesn't sound so bad.
