docs: // UpdateSMBFileShare API operation for AWS Storage Gateway.
  //
  // Updates a Server Message Block (SMB) file share.
  //
  // To leave a file share field unchanged, set the corresponding input field
  // to null. This operation is only supported for file gateways.
  //
  // File gateways require AWS Security Token Service (AWS STS) to be activated
  // to enable you to create a file share. Make sure that AWS STS is activated
  // in the AWS Region you are creating your file gateway in. If AWS STS is not
  // activated in this AWS Region, activate it. For information about how to activate
  // AWS STS, see Activating and Deactivating AWS STS in an AWS Region (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_enable-regions.html)
  // in the AWS Identity and Access Management User Guide.
  //
  // File gateways don't support creating hard or symbolic links on a file share.
  //
  // Returns awserr.Error for service API and SDK errors. Use runtime type assertions
  // with awserr.Error's Code and Message methods to get detailed information about
  // the error.
  //
  // See the AWS API reference guide for AWS Storage Gateway's
  // API operation UpdateSMBFileShare for usage and error information.
  //
  // Returned Error Codes:
  //   * ErrCodeInvalidGatewayRequestException "InvalidGatewayRequestException"
  //   An exception occurred because an invalid gateway request was issued to the
  //   service. For more information, see the error and message fields.
  //
  //   * ErrCodeInternalServerError "InternalServerError"
  //   An internal server error has occurred during the request. For more information,
