From 337e88d8909b1442956acfa351d48e30a272251c Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 14 Jan 2022 15:37:32 +0000 Subject: linux-user: Return void from queue_signal() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The linux-user queue_signal() function always returns 1, and none of its callers check the return value. Give it a void return type instead. The return value is a leftover from the old pre-2016 linux-user signal handling code, which really did have a queue of signals and so might return a failure indication if too many signals were queued at once. The current design avoids having to ever have more than one signal queued via queue_signal() at once, so it can never fail.
