nfs41: increment_{open,lock}_seqid
Unlike minorversion0, in nfsv4.1 the open and lock seqids need not be incremented by the client and should always be set to zero. This is implemented using a new nfs_rpc_ops methods - increment_open_seqid and increment_lock_seqid Signed-off-by: Rahul Iyer <iyer@netapp.com> Signed-off-by: Benny Halevy <bhalevy@panasas.com> [nfs41: check for session not minorversion] Signed-off-by: Andy Adamson <andros@netapp.com> Signed-off-by: Benny Halevy <bhalevy@panasas.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
