lockd: Adjust nlmclnt_lookup_host() signature to accomodate non-AF_INET
Pass a struct sockaddr * and a length to nlmclnt_lookup_host() to accomodate non-AF_INET family addresses. As a side benefit, eliminate the hostname_len argument, as the hostname is always NUL-terminated. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J.
