The POSIX ACL extension to NFSv4 defines FATTR4_POSIX_ACCESS_ACL and FATTR4_POSIX_DEFAULT_ACL for setting access and default ACLs via CREATE, OPEN, and SETATTR operations. This patch adds the XDR decoders for those attributes. The nfsd4_decode_fattr4() function gains two additional parameters for receiving decoded POSIX ACLs. CREATE, OPEN, and SETATTR decoders pass pointers to these new parameters, enabling clients to set POSIX ACLs during object creation or modification.
