Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 7bit X-Scanned-By: MIMEDefang 2.79 on 10.5.11.13 Precedence: bulk List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Hi, I have some code that analyzes x86_64 binaries (https://developers.redhat.com/articles/2021/08/09/debugging-function-parameters- dyninst#liveness_analysis) and list which function parameters are unused. I noticed that trace_raw_output_* functions have an unused flags argument. I assume this is is to make the argument list match up with some other function, but I couldn't see which function(s) the trace_raw_output_* functions are trying to match up with. Which functions are the trace_raw_output_* function's arguments trying to match? -Will Cohen
