Add new funtion svcauth_map_clnt_to_svc_cred_local which maps a generic cred to a svc_cred suitable for use in nfsd. This is needed by the localio code to map nfs client creds to nfs server credentials. Following from net/sunrpc/auth_unix.c:unx_marshal() it is clear that ->fsuid and ->fsgid must be used (rather than ->uid and ->gid). In addition, these uid and gid must be translated with from_kuid_munged() so local client uses correct uid and gid when acting as local server. Jeff Layton noted: This is where the magic happens. Since we're working in kuid_t/kgid_t, we don't need to worry about further idmapping.
