Neil, I've reproduced this and confirmed that the following addresses
the error:

 464 #ifdef CONFIG_FS_POSIX_ACL
 465         if (attr->na_pacl)
 466                 attr->na_aclerr = set_posix_acl(&init_user_ns,
 467                                                 inode, ACL_TYPE_ACCESS,
 468                                                 attr->na_pacl);
 469         if (!attr->na_aclerr && attr->na_dpacl && S_ISDIR(inode->i_mode))
 470                 attr->na_aclerr = set_posix_acl(&init_user_ns,
 471                                                 inode, ACL_TYPE_DEFAULT,
 472                                                 attr->na_dpacl);
 473 #endif

I can squash this change into ("NFSD: add posix ACLs to struct nfsd_attrs").
