[PATCH 11/25] NFS: Make nfs_alloc_client() take (sockaddr, len) instead of sockaddr_in

[PATCH 11/25] NFS: Make nfs_alloc_client() take (sockaddr, len) instead of sockaddr_in

[Chuck Lever]

To support non-IPv4 addresses, adjust the arguments and callers of
nfs_alloc_client() to pass in a "struct sockaddr *" and length instead of
a "struct sockaddr_in *".
