NFSv4: Support NFSv4 optional attributes in the struct nfs_fattr
Currently, filling struct nfs_fattr is more or less an all or nothing operation, since NFSv2 and NFSv3 have only mandatory attributes. In NFSv4, some attributes are optional, and so we may simply not be able to fill in those fields. Furthermore, NFSv4 allows you to specify which attributes you are interested in retrieving, thus permitting you to optimise away retrieval of attributes that you know will no change...
