From: Andy Adamson <andros@xxxxxxxxxx>
Define nfsd41_dec_ops vector and add it to nfsd4_minorversion for
minorversion 1.
Note: nfsd4_enc_ops vector is shared for v4.0 and v4.1
since we don't need to filter out obsolete ops as this is
done in the decoding phase.
exchange_id, create_session, destroy_session, and sequence ops are
implemented as stubs returning nfserr_opnotsupp at this stage.
[was nfsd41: xdr stubs]
[get rid of CONFIG_NFSD_V4_1]
