This feature addition provides a new parameter in pti_request_masterchannel() to allow the user to provide their own name to mark the request when the trace is viewed in a PTI SW trace viewer (like MPTA). If a name is not provided and NULL is provided, the 'current' process name is used. API function header documentation documents this.
